Which describes the volume of 1 mol of gas at standard temperature and pressure?

A
The volume is greater for a larger mass of gas.
B
The volume is the same for any gas.
C
The volume depends on the size of the container.
D
The volume varies with the pressure.

If the pressure, volume, and temperature of a gas are known, which can most likely be found by using the ideal gas law?

A
the molar amount of the gas
B
the partial pressure of the gas
C
the standard temperature and pressure

A graph of gas pressure versus the number of particles in a container is a straight line. Which other relationship will have a similar graph?

A
volume versus pressure, because they are also directly proportional
B
volume versus temperature, because they are also directly proportional
C
volume versus pressure, because they are also inversely proportional
