    Number of moles of Cl₂ = 0.3 mol

    Explanation:

    Given dа ta:

    Number of moles of Cl₂ = ?

    Pressure = 0.966 atm

    Volume = 8.00 L

    Temperature = 45°C

    Solution:

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

    PV = nRT

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

    Now we will convert the °C into K.

    Temperature = 45 + 273 = 318 K

    Now we will put the values in formula.

    n = PV/RT

    n = 0.966 atm * 8.00 L / 318 K * 0.0821 atm. L/mol. K

    n = 7.728/26.1078 / mol

    n = 0.3 mol
