Answer:
The correct answer is 2747.7 Cal/mol.
Explanation:
The molar heat of fusion is illustrated as the amount of heat required to dissolve 1 mole of a substance at its melting point.
The atomic mass of iron = 55.845 g/mol
The mass of iron given = 200 g
The number of moles of iron = 200 g / 55.845 g/mol
= 3.581 moles
The heat discharged = 9840 Cal
The molar heat of fusion = Heat discharged / number of moles
= 9840 Cal / 3.581 moles
= 2747.7 Cal / mol
