Ideal Gas Law Calculator

The equation of state of an ideal gas which is a good approximation to real gases at sufficiently high temperatures and low pressures; that is, PV = RT, where P is the pressure, V is the volume per mole of gas, T is the temperature, and R is the gas constant. The Ideal Gas Law (General Gas Equation) is the equation of state of a hypothetical ideal gas.
Ideal Gas Law
Select your field:
Temperature (T): K
Pressure (P): kPa
Moles Of Gas (n): moles
Volume (V): L
Gas Equation: PV = nRT

P = pressure,
V = volume,
n = moles of gas,
T = temperature,
R = 8.314 J K-1 mol-1, ideal gas constant.

Calculate the Volume of gas through Ideal Gas Law equation.
Temperature = 20 K
Pressure = 30 kPa
Moles of Gas = 2.50 moles

Apply Formula:
Gas Equation: PV = nRT

Volume = 55.43 L
