n moist air, the lighter water molecules have a greater rms average speed than the heavier nitrogen molecules. Calculate the difference in the two average speeds at 41 C.

A certain amount of chlorine gas was placed inside a cylinder with a movable piston at one end. The initial volume was 3.00 LL and the initial pressure of chlorine was 1.25 atmatm . The piston was pushed down to change the volume to 1.00 LL. Calculate the final pressure of the gas if the temperature and number of moles of chlorine remain constant.. (Figure 1) Express your answer with the appropriate units.

A sample of unknown gas effuses in 74.1 minutes. An equal volume of argon in the same apparatus at the same temperature and pressure effuses in 31.9 minutes. What is the molar mass (in g/mol) of the gas? (Do not include units in your answer. If you round during your calculation make sure to keep at least 3 decimal places. Report your answer to 1 decimal place.)

A student completes the experiment The Universal Gas Constant and obtains the following data for one trial. mass of magnesium (g): Initial gas volume (ml): Final gas volume (ml): Temperature (°C): Atmospheric pressure (inHg): 30.39 Calculate the universal gas constant, R, for this trial. Assume that the water levels inside and outside the eudiometer tube are the same; that is, assume Ah = 0.00 cm water. Give your answer to two decimal places in the units of L-torr-mol-1. K-¹. 1 in Hg = 25.4 mmHg 1 cm water = 0.735559 mmHg 1 mol Mg = 24.305 g Mg on i TABLE D-4 TEMP DEGA C T 0 1 2 3 4 amm 14.579 4.612 4.646 | 4.660 4.714 4.924 4.959 4.9955.031 15.068 5.291 5.329 5.367 5.406 15.445 15.683 5.723 | 5.7645.805 5.146 16.100 1 6.143 6.1866.2306-274 1 6.318 10.6 I 0.7 J L 1 LI 1 4.7484.783 4.818 1 4.853 I 4.888 1 5.104 | 5.141 | 5.178 5.216 | 5.253 5.484 5.523 5.563 1 5.60215.647 I 5.888 | 5.930 | 5.972 1 6.014 1.6. 7_1 5.363 | 6.407 6.453 I 6.498 1 6.823 | 6. 871 6.919 1 6.967 1 1 | 6.544 |…
