Question

Which describes the volume of 1 mol of gas at standard temperature and pressure?
The volume is greater for a larger mass of gas.
The volume is the same for any gas.
The volume depends on the size of the container.
The volume varies with the pressure

Answer 1

The best statement, I think, is that the volume is the same for any gas. If we assume we have an ideal gas, this statement is very valid since it has been established that at STP, where the temperature is 0 degrees Celsius and the pressure is 1 atm, the volume of 1 mole of gas is 22.4 L. 

Answer 2

THE VOLUME IS THE SAME FOR ANY GAS
