    Answer:

    c.) 22.4 L/1 mole

    Explanation:

    Using the general gas law equation as follows:

    PV = nRT

    Where;

    P = pressure (atm)

    V = volume (L)

    n = number of moles (mol)

    R = gas law constant (0.0821 Latm/molK)

    T = temperature (K)

    The standard values for a gas are as follows:

    Standard pressure of a gas = 1 atm

    Standard temperature of a gas = 273K

    According to the information in the question, n = 12.3 moles

    Using PV = nRT

    V = nRT/P

    V = 12.3 × 0.0821 × 273/1

    V = 275.68 L

    Based on this value of volume in liters for 12.3moles of Br gas, the volume per mole at standard temperature and pressure will be 275.68/12.3 = 22.4 Litres per mole. Hence, the answer is 22.4 L/1 mole.
