The Pressure of the mixture gas is equal to the sum of the pressure of the partial gases in a container” is the statement of Dalton’s partial pressures law. Calculate the pressure of combined gases with known values of temparature and mole of gas.

Calculator of Dalton’s Partial Pressure

Dalton's Law
Enter the values of 'moles of gases(n)' separated by comma
E.g: 100,24,150
Temperature(T): K
Moles of Gas(n): moles
Volume(V): L
Pressure(P): kPa

Formula of Dalton’s Partial Pressure



  • p1,p2,p3, …,pm = Partial pressures of the individual gases in the mixture.
  • V = volume,
  • T = temperature,
  • n1,n2,n3, …,nm=n is the total amount of gas of the m gases present in the mixture,
  • R = 8.314 J K-1 mol-1, ideal gas constant.

The Dalton’s law calculator is derived from the law of partial pressures.
