Question
The heat of fusion of aluminum is $3.95 \mathrm{kJ} / \mathrm{g}$. What is the molar heat of fusion of aluminum? What quantity of energy is needed to melt $10.0 \mathrm{g}$ of aluminum? What quantity of energy is required to melt $10.0 \mathrm{mol}$ of aluminum?
Step 1
The molar mass of aluminum is 27 grams per mole. Therefore, the molar heat of fusion is $3.95 \mathrm{kJ/g} \times 27 \mathrm{g/mol} = 106.65 \mathrm{kJ/mol}$. Show more…
