Ideal Gas Law Problems

Name:________________________

1. An aerosol spray deodorant can with a volume of 350 mL contains 3.2 g of propane gas (C3H8) as propellant. What is the pressure in the can at 20oC?

2. A helium gas cylinder of the sort used to fill balloons has a volume of 180 L and a pressure of 150 atm at 25oC. How many moles of helium are in the tank? How many grams?

3. If 15.0 g of CO2 gas has a volume of 0.30 L at 310 K, what is its pressure in atm?

4. If 18.0 g of O2 gas has a temperature of 350 K and a pressure of 550 mm Hg, what is its volume?
