    42050 J.

    Explanation:

    Data obtained from the question:

    Mass (M) of ethanol = 50g

    Heat of vaporisation (ΔHv) of ethanol = 841 J/g

    Heat (Q) =.?

    The heat required to boil 50g of ethanol can be obtained as follow:

    Q = MΔHv

    Q = 50 x 841

    Q = 42050 J.

    Therefore, the heat required to boil 50g of ethanol is 42050 J.
