# How do you calculate the molar volume of a gas at STP?

##### 1 Answer

The Molar Volume of a gas at STP is a constant using Avogadro's value of 22.4 L/mol.

To calculate this we can use the Ideal gas law of

At STP (Standard Temperature and Pressure)

P = 1 atm

V = ?

n = 1 mol

R = 0.0821

T = 273 K

I hope this was helpful.
