If 34 g of a solid of mol mass = 174 g/mol requires 21.3 kJ to melt it, what is the molar heat of fusion in kJ/mol?

Question

Quizplus · Accepted Answer

The molar heat of fusion is calculated by dividing the energy required to melt the solid by the number of moles of the solid. The number of moles is given by the mass of the solid divided by its molar mass. Therefore, the molar heat of fusion is (21.3 kJ) / (34 g / 174 g/mol) = (21.3)(174/34) kJ/mol.

If 34 G of a Solid of Mol Mass =
