## 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**

- First, determine the number of moles of gas.
- The number of moles of gas is given as 140.

- Next, determine the temperature (C).
- The temperature (C) is calculated as: 50.

- Next, determine the pressure (Pa).
- The pressure (Pa) is found to be: 30.

- 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)
