    Here's what I find

    Explanation:

    You don't use ΔHfus. You use ΔHvap

    There are some preliminary calculations:

    Use the density of the liquid to calculate its mass. Use the molar mass to calculate the moles (n)

    The formula for the heat (q) absorbed during vaporization is

    q = nΔHvap

    Insert your numbers into the formula, do the calculation, and you have the answer.
