    Energy required is 4.147 kj.

    Explanation:

    Given dа ta:

    Mass of ice = 12.4 g

    Temperature = 0°C

    Molar heat fusion for ice = 6.02 kj/mol

    Energy required to melt = ?

    Solution:

    Formula:

    q = n * ΔH

    q = heat

    n = number of moles

    ΔH = enthalpy

    First of all we will calculate the number of moles.

    Number of moles = mass / molar mass

    Number of moles = 12.4 g / 18 g/mol

    Number of moles = 0.69 mol

    Now we will put the values in formula.

    q = n * ΔH

    q = 0.69 mol * 6.02 kj/mol

    q = 4.147 kj
