This ideal gas law reference table shows the pressure (p) for a range of amount of gas (n) values, assuming a temperature (t) of 273 K and a volume (v) of 22.4 L. Every figure is computed with the same engine that powers our Ideal Gas Law Calculator, so the numbers are exact.

Amount of gas (n)Pressure (P)
0.25 mol0.2500
0.5 mol0.5000
0.75 mol0.7501
1 mol1.0001
1.5 mol1.5001
2 mol2.0001
3 mol3.0002
5 mol5.0003
7 mol7.0005
10 mol10.0007

How to use this table

Find the row closest to your amount of gas (n) and read across to the pressure (p). For a value between two rows, the real figure sits between them — or enter your exact numbers in the Ideal Gas Law Calculator for a precise answer.

Need a value that is not in the table? — the Ideal Gas Law Calculator does it instantly, for free, with the formula and a worked example built in.
