5 mar 2014 · Using the Ideal Gas Law, you would find the volume of 1 mole of a gas at Standard Temperature and Pressure (STP). STP = 1 atm of pressure and 273 K for temperature P = 1 atm
How to calculate the molar volume of an ideal gas at STP. You can use the ideal gas volume calculator to find the molar volume of an ideal gas at standard temperature and pressure (STP) – or any other temperature or pressure. All you need to do is set the amount of substance variable to 1 mole.
Enter the volume, temperature, and pressure in their respective fields and tool will calculate the STP volume and moles of substance. The STP calculator is an efficient tool to represent the number of moles and the volume of a substance at the standard temperature and pressure.
The most common example is the molar volume of a gas at STP (Standard Temperature and Pressure), which is equal to 22.4 L for 1 mole of any ideal gas at a temperature equal to 273.15 K and a pressure equal to 1.00 atm.
This online calculator calculates the molar volume of an ideal gas at different conditions (different temperature and pressure). You can read about the formula and the most commonly used conditions below the calculator.
Be aware that using molar volume (like in the problems below) only works at STP. If you have non-standard conditions, you MUST use PV = nRT. Example #1: you have 2.00 mol of dry H 2 at STP.
Molar volume at STP can be used to convert from moles to gas volume and from gas volume to moles. The equality of \(1 \: \text{mol} = 22.4 \: \text{L}\) is the basis for the conversion factor. Example \(\PageIndex{1}\): Converting Gas Volume to Moles
