    The formula for this is: \(\sf heat~required=amount ~of~X*heat~of~fusion \) the symbols you'll see typically will be: \(\sf q=m*\Delta H_{fusion}\) m is mass (grams or kilograms), or sometimes you'll see \(n\) instead which means moles. Pay attention to the units of the heat of fusion, that determines whether its mass or moles.

    So to solve the problem, rearrange the formula and plug in your values. Note that it may be required for you to make conversions if they want the heat of fusion in certain units.
