experimentally determine the Universal Gas Constant “R”. Amedeo Avogadro hypothesized that all gases of equal volume‚ temperature and pressure would contain equal amounts of moles. This idea that volume is directly proportional to moles sprung from other similar hypotheses. Robert Boyle found that pressure and volume are inversely proportional‚ meaning as pressure increases‚ volume decreases and visa versa. P1V1=P2V2

Introduction Molar volume is the name given to the volume that one mole of any gas occupies at standard temperature and pressure. In chemistry‚ many of the materials worked with are gases. It is often easier to measure the volume of a sample of gas‚ rather than determine its mass. The main purpose of this lab is to determine the molar volume of hydrogen gas experimentally in order to compare it to the theoretical molar volume of ideal gases. In this experiment‚ a known mass of magnesium is reacted

Barometer * Sink Full of Water Purpose The purpose of this experiment is to determine the molar mass of butane using Dalton’s Law of Partial Pressures and the ideal gas law. Hypothesis My hypothesis is that as we complete the experiment‚ we will be able to correctly use the air and water temperatures‚ volume of gas‚ and barometric pressure to correctly calculate the molar mass of butane Procedure At first‚ gathered all of the materials. Fill a sink full of water and place a thermometer

the paint is being fired. If velocity adjustment is necessary‚ Use a 5/32-inch allen wrench on the adjuster in the bottom of the vertical regulator‚ turn clockwise to increase the velocity/pressure‚ and counter-clockwise to decrease. Take three or four shots after every adjustment to allow the gas pressure inside the EnvyTM to stabilize. Adjust until the marker is firing consistently within the limits for the field where you are playing. For safety reasons‚ never adjust the EnvyTM to fire at

data using Charles’ quantitative law of V1/T1=V2/T2. Obtain a reference of pressures effects on gas using Boyle’s law using a gas sample of standard “air” within a syringe and measuring pressures increase and decrease in association to changing volume. Measurements are obtained through microLAB sensors and graphed using microLAB software where a correlation coefficient of P vs. 1/V can be determined to represent pressure and volume’s relationship to each other in the experiment.
