    27.22dm³

    Explanation:

    Given parameters:

    number of moles = 1 mole

    temperature = 50°C, in K gives 50+273 = 323K

    Pressure = 98.6kpa in atm, gives 0.973atm

    Unknown:

    Volume of the gas = ?

    Solution:

    Since the unknown is the volume of gas, applying the ideal gas law will be appropriate in solving this problem.

    The ideal gas law is mathematically expressed as;

    Pv = nRT

    where P is the pressure of the gas

    V is the volume

    n is the number of moles

    R is the gas constant

    T is the temperature

    Input the parameters and solve for V;

    0.973 x V = 1 x 0.082 x 323

    V = 27.22dm³
