    n = 0.072 mol

    Explanation:

    Given dа ta:

    Volume of gas = 3.80 L

    Temperature of gas = 320 K

    Pressure of gas = 0.496 atm

    Number of moles of Ar gas = ?

    Solution:

    The given problem will be solve by using general gas equation,

    PV = nRT

    P = Pressure

    V = volume

    n = number of moles

    R = general gas constant = 0.0821 atm. L / mol. K

    T = temperature in kelvin

    Now we will put the values.

    n = PV/RT

    n = 0.496 atm * 3.80 L / 0.0821 atm. L / mol. K * 320 K

    n = 1.88 / 26.27 / mol

    n = 0.072 mol
