    Answer:

    0.062mol

    Explanation:

    Using ideal gas law as follows;

    PV = nRT

    Where;

    P = pressure (atm)

    V = volume (L)

    n = number of moles (mol)

    R = gas law constant (0.0821Latm/molK)

    T = temperature (K)

    Based on the information provided;

    P = 152 Kpa = 152/101 = 1.50atm

    V = 0.97L

    n = ?

    T = 12°C = 12 + 273 = 285K

    Using PV = nRT

    n = PV/RT

    n = (1.5 × 0.97) ÷ (0.0821 × 285)

    n = 1.455 ÷ 23.39

    n = 0.062mol
