Determine the total volume of gas must be collected
At 29.0°C the Helium is collected over water 1.00 atm total pressures. Determine the total volume of gas must be collected to get the .542 g of helium, at 25°C the vapor pressure of water is 23.8torr.

When the O2(g) was dried water vapor removed, the gas has a volume of 1.93 L at 25°C and 785 torr. A 2.01 L sample of O2(g) was collected overwater at a total pressure of 785 torr and 25°C. Explain the vapor pressure of water at 25°C.

For a perfect gas of molar mass M, Deduce the relation among the pressure and mass density. Confirm graphically, using the following data on diethyl ether at 25 degrees that perfect behavior is reached at low pressures.
Explain this result to a person who is familiar with hypothesis testing in general, such as with the t test for independent means, but knows nothing about chi-square tests.
