Question

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.

Answer 1

B) The volume is the same for any gas.

Step-by-step explanation:

Considering the ideal gas equation as:-

`PV=nRT`

where,

P is the pressure

V is the volume

n is the number of moles

T is the temperature

R is Gas constant having value = 8.314 J/ K mol

At STP,

Pressure = 1 atm

Temperature = 273.15 K

So, applying the values we get that 1 mole of any gas occupies a volume of 22.4 L

Thus, correct option is:- B) The volume is the same for any gas.
