    Investigation to Determine the Relative Atomic Mass of Lithium Introduction My aim of this experiment will be to determine the R.A.M using two separate methods In the first method I will dissolve a piece of lithium of a known mass in water, I will then collect the hydrogen gas produced, which can be used to calculate the relative atomic mass of Lithium. The balanced equation of our reaction is shown below; [IMAGE]2Li + 2H2O 2LiOH + H2 In the second method I will do a titration

    Determination of Relative Atomic Mass of Lithium Evaluation: In general the accuracy of the experiments was good. However with practice, the accuracy could be improved; accuracy being how close the results are to the real answer. I think I have carried pit the experiment as well as I possibly could at the time with the given conditions and time period allowed. I have gained precise results from the practical. However, looking back at the analysis section, the relative atomic mass values I found

    Determining the Relative Atomic Mass of Lithium An experiment has been carried out to determine the relative atomic mass of Lithium by using two different types of methods The first method that was carried out was to determine the volume of Hydrogen produced. In this experiment a fixed amount of Lithium was used, in my case it was 0.11g. At the end of this experiment, the volume of Hydrogen gas I collected was 185cm³. Then using the solution of lithium hydroxide made from experiment

    An Investigation into the Atomic Mass of Lithium There are two methods that can be used to determine the atomic mass of a Group 1 metal. These are best described by the reactions that take place during these methods. Method 1: 2Li(s) + 2H20(l) è 2LiOH(aq) + H2 (g) For the first reaction, the equipment must be set up as detailed in the attached sheet. A mass of lithium must be taken and weighed, the results recorded. This mass is then to be added to the test tube, and the bung replaced

    Investigating the Relative Atomic Mass of Lithium Background information I’m going to produce a piece of coursework, which determine the relative atomic mass of lithium. Two methods are going to be used to approximate the relative atomic mass of lithium. 1) In the first method the RAM (Relative atomic mass) of lithium is determined by the Volume of hydrogen gas produced. 2) In the second method the RAM of lithium is determined by titrating the lithium hydroxide produced. To

    positive charge, electrons have a negative charge while neutrons are neutral and carry no charge. The only similarities, which 2 of the particles have, are protons and neutrons and their mass is equal to the mass of an atom of hydrogen. While scientifically we call this mass one atomic mass unit. The mass of an atom depends on the amount of protons and neutrons the atom contains and the arrangement of particles within the atom. The arrangement of the particles within an atom depend on how

    to the cathode, the mass of the anode to the cathode, the mass of the anode decreases whilst the mass of the cathode increases. I can support the point I've made above by faradays law which is: Faraday's Second Law of electrolysis states that: "The mass of an element deposited by one Faraday of electricity is equal to the atomic mass in grams of the element divided by the number of electrons required to discharge one ion of the element." Hypothesis: The mass of the anode should

    Copper has many chemical properties that make it unique. The Atomic number of copper is 29. An Atomic number is a measure of the amount of protons in the nucleus of an atom. Protons are sub-atomic particles, which have a positive charge. The Atomic mass of copper is 63.546. The Atomic mass is a measure of how many neutrons and protons are in an atom. Neutrons are sub- atomic particles, which have no charge. Thus, using the Atomic mass and Atomic number of Copper, we can determine that it has 29 proton
