Enter the number of moles of gas into the calculator to determine the volume at standard temperature and pressure.

Volume at Standard Temperature and Pressure Formula

The following formula is used to calculate volume at standard temperature and pressure: 

V = n*R*T / P
  • Where V is the volume (L)
  • n is th enumber of moles
  • R is the gas constant (8.314472 J/mole*K)
  • T is the standard temperature ( 0C = 273 K)
  • P is the standard pressure (1 atm = 101,325 pascals)

What are standard temperature and pressure?

A standard temperature and pressure is a system used to simplify calculations by relating temperature and pressure to constant values.

These values are 0 degrees Celsius for temperature and 1 atmosphere for pressure.

These are equivalent to 273 degrees kelvin and 101,325 pascals respectively.

How to calculate volume at standard temperature and pressure?

The following example outlines the steps required to calculate the volume of a gas at standard temperature and pressure.

First, determine the number of moles of gas. In this example, there are 20 moles of gas.

Next, using the values of standard temperature and pressure, along with the gas constant and number of moles, calculate the volume.

V = n*R*T / P

V = 20*8.314472*273/ 101,325

V = .448 Liters
