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.

    Formula

    Gas Equation: PV = nRT

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

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

    Solution:
    Apply Formula:
    Gas Equation: PV = nRT

    Volume = 55.43 L
