  3. Check the method and assumptions below before using the result.

The method, explained

Pressure = nRT/V, with R = 8.31446261815324 J/(mol·K).

A WORKED EXAMPLE

Using amount of gas = 1 mol, absolute temperature = 298.15 K, volume = 0.024 m³, the result is 103289.876 Pa. Change these example inputs to match your task; use the method above to check each step.

What to keep in mind

Ideal gas law is an approximation for real gases. An idealized educational model using the stated SI units. Real systems may need additional forces, losses or experimental measurements. Not a safety or equipment specification.

Common questions

Which inputs does this calculation need?
