1.
A sample of CO
2
with a pressure of 76.0 mm Hg in a volume of 0.200 L is
compressed so that the new pressure of the gas is 90.0 mm Hg. What is the new
volume of the gas? Assume that temperature is constant.
2.
Suppose you have a sample of CO
2
in a gastight syringe. The gas volume is 38.0
mL at 25˚C. What is the final volume of the gas if you hold the syringe in your
hand to raise its temperature to 40˚C?
3.
You have a 34.0 L cylinder of helium at a pressure of 110 atm and a temperature
of 43˚C. How many balloons can you fill, each with a volume of 26.0 L, on a day
when the atmospheric pressure is 600 mm Hg and the temperature is 15˚C?
4.
A hot air balloon is filled with 2000 grams of H2. If the temperature of the gas is
32˚C and its pressure is 800 mm Hg, what is the volume of the balloon?
5.
A .306 gram sample of a gaseous compound has a pressure of 400 mm Hg in a
volume of 225 mL at 27˚C. What is its molar mass?
6.
You choose to make some deuterium gas, D2, for use in an experiment and one
way to make is to react heavy water, D2O, with the active metal lithium.
