Asample of iron (fe) with a mass of 200.0 g releases 9,840 cal when it freezes at its freezing point. what is the molar heat of fusion for iron?

The molar hat of fusion for iron can be calculated by dividing the heat released to the mass of the sample. In this problem, we are given with 9840 calories of heat and 200 gram sample. The answer for this problem by simple division is 49.2 cal/ g iron.
