If you were asked to use 0.230 grams of anthracene (MW=178.23) and 0.130 grams of maleic anhydride (MW=98.06) in 15.0 mL of mineral spirits (assume a MW of 400 g/mol), what would be your limiting reagent?

If the heat of fusion of water is 3.4 × 10^2 joule/gram, the heat energy amount required to change 15.0 grams of ice at 0°c to 15.0 grams of water at 0°c is 5100 joule (5100 = 3.4 x 10^2 x 15).

The problem above can be solved by using the heat of fusion formula. The formula for calculating the heat of fusion described as C = q/m, where: C is the heat of fusion, q is the amount of heat energy required, and m is the mass of the object.
