determined that the best way to conduct this experiment is to do a titration. This will allow me to determine the amount of impure citric acid required to neutralise a known volume of 1.0 M sodium hydroxide. Consequently, by calculating the correct volume of pure citric acid that would be required to neutralise this volume of sodium hydroxide, I can calculate the percentage purity of the citric acid. Calculating the Amount of Citric Acid ------------------------------------- In order
below this it shouldn't be a problem. Method: To perform the titration the first thing that needs to be done is to dilute the HCl to a suitable concentration, to increase the accuracy of the results it would be helpful if the volume of the alkali equalled the volume of the acid used. We know that the concentration of the alkali is close to 1g/dm‾, which is roughly equal to 0.013mol by using the equation Mass = Mole * RAM.
made up of three trapezium prisms and a half sphere. So to find the volume of the oil glass bottle you would need to find the volume of all three truncated cones and the volume of the half sphere and plus them all together. To find the volume of the truncated cones, you need to use the formula V = π [s (R + r) + R2 + r2], this will give you the volume for all the truncated cones. Also to find the volume of the half sphere is two-thirds times pi times radius3 (2/3 x π x r3). Once these volumes have been
Expansion and Contraction of Materials When most materials are heated they expand and this increase their volume. One example of expansion is the fitting of the starter ring gear to the flywheel. The gear is heated until it expands sufficiently to pass over the rim of the flywheel, and when it is cool the gear tries to return to its original size, this gripping the flywheel with considerable force. All metals do not expand equally when heated through the same range of temperature, e.g. aluminium
density by measuring mass and volume. Finding which substance is the most dense by comparing different substances. Background: The density of water is 1 g/mL. In order to find density, you must do mass divided by volume. You find solid volume by multiplying the length by width by height or by using displacement. You find mass by weighing the substance. In previous experiments, it is seen that alcohol dissolves faster than water. Hypothesis: If the density of three substances is found, then the
INTRODUCTION Some Types of measurements include length, volume, mass and temperature. Length is the measurement or extent of something from end to end. Volume is the amount of space that a substance or object occupies, or that is enclosed within a container. Mass, is the quantity of matter that a body contains, as measured by its acceleration under a given force or by the force exerted on it by a gravitational force. Temperature, is the degree or intensity of a het present in a substance or object
divided into three volumes, each taking place at a distinct time. Volume I highlights the correspondence in letters between Robert Walton, an Arctic seafarer, and his sister, Margaret Saville. Walton's letters to Margaret basically explain his expedition at sea and introduce Victor Frankenstein, the protagonist of the novel. Volume II is essentially Frankenstein's narrative, told in his point of view, with much action, death, and many more characters. There are a few chapters within this volume in which
of how Changing the Volume of Water in a Container Affects Its Rate of Heat Loss Aim : To investigate how changing the volume of water in a container affects its rate of its heat loss. The variable of this investigation is the volume of water which is put in the container. What I already know: I already know that the larger the volume of water there is the less heat loss occurs. I can tell this from my previous pilot experiment where I investigated, if the volume of water in a beaker
become cloudy and make a cross below it to disappear. Method: Apparatus Hydrochloric Acid Sodium Thiosulphate Distilled Water 250cm ³ Beaker- I need a beaker big enough to see the cross and although the 100cm³ would be perfect volume wise I would prefer to use a bigger one so I can fit the cross under it and also be able to pour the reactants into it without any spillage 100cm ³ Measuring Cylinder- I have decided to use this cylinder for the Sodium Thiosulphate. I am only
grad. cylinder., and a 25 ml pipette were determined by transferring each type to a tared 50 ml beaker. The density of copper was determined through volume displacement in water. The pipette was fond to be the most precise with a mean volume of 24.843±0.184ml. While the 25 ml cylinder had a volume of 24.601±0.708 ml and the 50 ml beaker had a volume of 24.074±1.98 ml. The density of copper was found to be 9.190±0.836, with an accuracy of 2.567%. The difference in density measurements could be due
following in the footsteps of Plato, Socrates, and Euclid. Historians call him "the wise one," "the master" and "the great geometer". Although he was also a scientist and inventor, it was his work in mathematics that has ranked him as one of the three most important mathematicians in history, along with Sir Isaac Newton and Carl Friedrich Gauss. Further, he was one of the first scientists to perform experiments to prove his theories. Archimedes’ discoveries in mathematics continue to have an impact
Aim: - An experiment on how a volume of nitrogen gas is affected by the pressure exerted on it. INTRODUCTION: Gases are composed of molecules and are not held by intermolecular forces of attraction. They move about in random directions constantly colliding with one another and with their container walls without loss of kinetic energy. Thus, the collision of gases is said to be elastic since kinetic energy is not lost. As collision between gas particles become faster and more frequent, the impact
volumetric apparatus’s. Accuracy in volume measurements are significant in analytical chemistry but all volumetric glassware have errors and obscurities linked with the measurements observed. Miniscule damage in a glassware due to aging, abuse and chemicals can create systematic errors in the observational measurements. Volumetric pipets and burets can be used for fairly accurate measurements if they’re standardized correctly. The purpose of this exercise is to measure volume and mass, to evaluate precision
graduated cylinder. Using five grams was too low of an amount to measure and twenty grams seemed too much. Also, using ten grams for each metal made the procedure quick and simple to complete. The volume was picked out to 50 mL because this amount of volume was much easier to measure than a really low volume like 10 mL. Since the graduated cylinder is numbered by a factor of 10 mL, it was easier to read a 50 mL as opposed to a 73 mL. The calculated density for the unknown metal A seemed to be aluminium
My lesson was taught to a group of fifth grade math students at Athens Intermediate School, located in Athens, Al. The lesson focus was on volume. The Alabama course of study standard that was addressed was to understand concepts of volume and relate volume to multiplication and to addition. During the lesson I focused on some areas of interest: Were the lesson standards and skills met? What individuals had trouble, and which individuals did well and why? What were some strengths and weakness for
50cm, which he uses to make drains. The semi-circle is the best shape for a drain. Prove this. I will prove this by comparing its volume to that of other shapes. On older houses there are semi-circular drains but on newer houses there is fancier ones like pentagon shapes. Is this because they are better or is it simply for design? To find the volume of a 3D object I have to find the area of a cross section and then multiply that by the length of the object. To make it easier IÂ’m going
electronic balance. Introduction Density is the amount of substance per unit volume. The density, is a measurement of how the substance is tight together. The Greek scientist Archimedes is the person who discovered the fundamental of the density. The density of an object is calculated using this equation: D=M/V Equation (1) where D is the density, M is the mass of the object and V is the volume of the object. The volume of a rectangular object can be expressed in the equation: V=LWH Equation
Volumetric glassware are containers that have been calibrated at specific temperature to deliver or contain very precise amount of liquid. In order to ensure the accuracy and precision of the glassware’s then a calibration must be done. The assumption of volume for volumetric glassware is dependent on the cleanliness of the surface. Although accuracy is more important in TD (to deliver) glassware there should still be considerations for the messy and unpleasant substances on the surface of the TC (to contain)
Investigating the Volume of an Open Box The aim of this coursework is to investigate the volume of an open box constructed by one piece of rectangular card that has all four corners having had squares cut out of them. Firstly I will be studying the volume whilst changing the side of one length of the cut out square and the size of the original rectangle card. After I have investigated this relationship I will try to find out the formula for finding the cut size to get the largest volume for any specified
