Recommended: Chapter 4 elements and the periodic table

Objectives:
To determine the molar mass of butane gas experimentally
To compare the experimental value with the value obtained theoretically

Theory: The molar mass of butane gas (C4H10)can be obtained theoretically by using a periodic table, but by rearranging the ideal gas law equation (PV = nRT) to n =PVRT, the experimental molar mass of butane gas can be found. In the equation, P= pressure in atmosphere, V= volume in liters, n= moles, R= 0.0821, and T= temperature in kelvin. To find the values for the equation, the mass of the butane released from a pressurized container and the volume of that gas will be found, and the method of water displacement at room conditions will be used to find the rest of the values. Then, the molar mass will

  • 4-Tert-Butylcyclohexanone Lab Report

    1799 Words  | 4 Pages

    The goal of this two week lab was to examine the stereochemistry of the oxidation-reduction interconversion of 4-tert-butylcyclohexanol and 4-tert-butylcyclohexanone. The purpose of first week was to explore the oxidation of an alcohol to a ketone and see how the reduction of the ketone will affect the stereoselectivity. The purpose of first week is to oxidize the alcohol, 4-tert-butylcyclohexanol, to ketone just so that it can be reduced back into the alcohol to see how OH will react. The purpose of second week was to reduce 4-tert-butylcyclohexanol from first week and determine the effect of the product's diastereoselectivity by performing reduction procedures using sodium borohydride The chemicals for this lab are sodium hypochlorite, 4-tert-butylcyclohexanone

    In this lab 4-tert-butylcyclohexanone is reduced by sodium borohydride (NaBH4) to produce the cis and trans isomers of 4-tert-butylcyclohexanol. Since the starting material is a ketone, NaBH4 is strong enough to perform a reduction and lithium aluminum hydride is not needed. NaBH4 can attack the carbonyl group at an equatorial (cis) or axial (trans) position, making this reaction stereoselective. After the ketone is reduced by the metal-hydride, hydrochloric acid adds a proton to the negatively charged oxygen to make a hydroxyl group. The trans isomer is more abundant than the cis based on the results found in the experiment and the fact that the trans isomer is more stable; due to having the largest functional groups in equatorial positions.

  • Lab Report Determining the Molar Volume of a Gas

    The first step that we took to accomplish our goal was to put on our safety goggles and choose a lab station to work at. We received one 400ml beaker, one polyethylene pipet, two test tubes with hole rubber stoppers, two small pieces of magnesium (Mg), one thermometer and a vial of hydrochloric acid (HCl). We took the 400ml beaker and filled it about 2/3 full of water (H20) that was 18 OC. Then we measured our pieces of Mg at 1.5 cm and determined that their mass was 1.36*10-2 g. We filled the pipet 2/3 full of HCl and poured it into one of the test tubes. Then, we covered the HCl with just enough H2O so that no H2O would be displaced when the stopper was inserted. After inserting the stopper, we placed the Mg strip into the hole, inverted the test tube and placed it in the 400ml beaker. HCl is heavier than H2O, so it floated from the tube, into the bottom of the beaker, reacting with the Mg along the way to produce hydrogen gas (H2). We then measured the volume of the H2, cleaned up our equipment and performed the experiment a second time.

  • The Pressure Of A Gas Law

    On earth, substances tend to exist in one of three phases; either a solid, liquid, or gas. While solids and liquids have defining factors such as volume, and for solids only, a shape, gases exhibit neither of these. Gases naturally take the shape of and expand into the volume of the container, and change when placed in different surroundings. As gases are constantly moving around and colliding with the walls, they exert a force, or pressure, on the walls of its container. Pressure is one of the characteristic behaviors that gases exhibit, but due to their nature, various factor effect the pressures that a gas can exert. Towards the end of the eighteenth century, scientist began to stumble upon these various factors that affect gases, especially

  • Acethene And Butane Research Paper

    Butane seemed to be a very stable and almost boring molecule. The atoms were just sharing electrons with no real net charge causing the molecule to be non-polar. The second molecule seems to have much more happening. The dipole on the Oxygen atom makes it seem much more complex. The main difference between these to is the fact that acetone is a liquid and butane is a gas causing acetones density to be substantially higher than butane. Both of these substances would float on top of water. The only main difference between the two molecules’ molecular formula is that acetone has an oxygen atom. Besides the one oxygen atom, they are essentially very similar atoms, but that atom completely changes its properties. That one atom managed to completely

    The equations of states such as the ideal gas can be used to relate temperature, pressure and the number of moles of gas present in the bulb. In this thermometer the number of moles of gas inside the bulb remains constant leaving only two variables which are temperature and pressure. The correlation between the pressure and temperature can be made using the ideal gas equation. In the ideal gas equation, the temperature of the gas is directly proportional to the vapor pressure of gas inside the bulb. However, this relation might not be linear because all gases do not obey the ideal gas law. In the...
