please help! thank you
A certain mass of nitrogen gas occupies a volume of 8.82 L at a pressure of 7.80 atm. At what pressure will the volume of this sample be 11.20 L? Assume constant temperature and ideal behavior. A sample of an ideal gas has a volume of 3.60 L at 14.40 °C and 1.60 atm. What is the volume of the gas at 19.80'C and 0.986 atm? V = If 73.5 mol of an ideal gas occupies...

6. While cleaning out a laboratory, a chemist found an unlabeled gas cylinder containing 7.5 x 10 mL of gas at 20.5°C at 1.50 atm of pressure. The chemist believed the mystery gas could be pure He, Ne, Ar, or Kr. Towards this end, the gas was found to have a mass of 1.88 g. What is the molar mass? What is the most likely identity of the mystery gas? 7. Assuming all gas is...

Ideal Gas Problems 1.(20pts). What is the approximate mass of the earth's atmosphere. Recall Newton's 2 law is F=mass x acceleration and that the Area of a sphere is 4xr? Data: The radius of the earth is 6.37 x 10 m. Take the average pressure at the surface of the earth to be 1.00 atm, and the average acceleration due to gravity as 9.80665 m/s.

chpt.9 pg 11: Pressure and temperature affect the amount of space between gas molecules, which affects the volume and, therefore, the density of the gas since density=massvolume The molar mass of a substance, however, is a constant and can be used to identify an unknown gas sample. Molar mass is found by dividing the mass of a sample (in grams) by the number of moles in that sample. The number of moles of gas can be calculated using the ideal...
