Ideal Gas Law Calculator (PV = nRT)

Your details

Enter the other three values and the calculator rearranges PV = nRT to find this one.

Volume (L)22.4
Temperature (K)273.15

Solved for amount of gas: 0.9994.

  • At 1 atm, 22.4 L and 273.15 K this sample holds 0.9994 mol (601,838,744,903,202,800,000,000 molecules).
  • Temperature must be absolute (kelvin); the calculator converts °C or °F for you before applying PV = nRT.
  • Its molar volume here is 22.414 L/mol (an ideal gas is 22.414 L/mol at 0 °C and 1 atm).

Next stepSwitch the "Solve for" dropdown to find any of pressure, volume, amount or temperature from the other three.
