Problem 3.1:
What is the density of carbon dioxide at 298 K and 1.0 atm?
Problem 3.2:
10 L of an unknown gas has a mass of 10.8 grams at a temperature of 310 K and
1.2 atm. What is the molar mass of the gas?
Problem 3.3:
A syringe of 0.010 mol O
2 and a syringe of 0.060 mol H
2 are forcibly
injected into an evacuated glass jar of volume 1.0 L and temperature 273 K.
What is the total pressure, and what are the partial pressures, of O
2 and
H
2?
Problem 3.4:
The volumes of containers A and B are kept separate by a stopcock. Both
containers have a volume of
10
-3 m
3 and are at a temperature of 273 K. The gas a in container A is
at a pressure of
2.00×105 Pa. The gas b in container B is at a pressure of
1.00×105 Pa.
What are the partial pressures
of a and b after the stopcock has opened and the system has equilibrated?
