    n = 0.34 mol

    Explanation:

    Given dа ta:

    Given temperature = 789 K

    Pressure = 765 torr (765/760 = 1.0 atm

    Volume of container = 22.0 L

    Number of moles of gas = ?

    Solution:

    Formula:

    PV = nRT

    n = PV/RT

    n = 1.0 atm * 22.0 L / 0.0821 atm. L/mol. K * 789 K

    n = 22.0 L. atm / 64.8 atm. L/mol

    n = 0.34 mol
