Enter the number of moles of gas, the temperature (C), and the pressure (Pa) into the Gas Volume Calculator. The calculator will evaluate and display the Gas Volume.

## Gas Volume Formula

The following formula is used to calculate the Gas Volume.

GV = n*R*T/P
• Where GV is the Gas Volume (m^3)
• n is the number of moles of gas
• T is the temperature (C)
• R is the universal gas constant (8.314 J/mole-C)
• P is the pressure (Pa)

## How to Calculate Gas Volume?

The following example problems outline how to calculate Gas Volume.

Example Problem #1

1. First, determine the number of moles of gas.
1. The number of moles of gas is given as 140.
2. Next, determine the temperature (C).
1. The temperature (C) is calculated as: 50.
3. Next, determine the pressure (Pa).
1. The pressure (Pa) is found to be: 30.
4. Finally, calculate the Gas Volume using the formula above:

GV = n*R*T/P

Inserting the values from above yields:

GV = 140*8.314*50/30 = 1939.93 (m^3)

Example Problem #2

The variables needed for this problem are provided below:

number of moles of gas = 185

temperature (C) = 874

pressure (Pa) = 93

Entering these values and solving gives:

GV = 185*8.314*874/93 = 14,454.73 (m^3)
