実例

Example: With Pressure P (atm) — blank if unknown = 1, Volume V (L) — blank if unknown = 22.4, Moles n — blank if unknown = 1, the Ideal Gas Law Calculator gives Unknown: T, Value: 272.9798.

よくある質問

What units does this expect?

Pressure in atmospheres, volume in liters, amount in moles, and temperature in Kelvin.

What is R?

The universal gas constant, 0.0821 L·atm/(mol·K) in these units.

What inputs does the Ideal Gas Law Calculator need?

You'll need to provide: Pressure P (atm) — blank if unknown, Volume V (L) — blank if unknown, Moles n — blank if unknown, Temperature T (K) — blank if unknown. All fields use sensible defaults, so you can see a working example immediately and then adjust the values to match your own numbers.

How accurate is the Ideal Gas Law Calculator?
