    V = 80.65L

    Explanation:

    Volume = ?

    Number of moles n = 5 mol

    Temperature (T) = 393.15K

    Pressure = 1520mmHg

    Ideal gas constant (R) = 62.363mmHg. L/mol. K

    According to ideal gas law,

    PV = nRT

    P = pressure of the ideal gas

    V = volume the gas occupies

    n = number of moles of the gas

    R = ideal gas constant (note this can varies depending on the unit of your variables)

    T = temperature of the ideal gas

    PV = nRT

    Solve for V,

    V = nRT / P

    V = (5 * 62.363 * 393.15) / 1520

    V = 80.65L

    The volume the gas occupies is 80.65L
