How many kJ of heat are needed to completely melt 95.3 g of copper metal,given that the metal is at its melting point? The heat of fusion for this metal is 13.1 kJ/mole

Question

Quizplus · Accepted Answer

The heat of fusion is the amount of heat required to melt one mole of a substance. The heat of fusion for copper is 13.1 kJ/mole. To find the amount of heat required to melt 95.3 g of copper, we need to first convert the mass to moles:95.3 g Cu * (1 mol Cu / 63.55 g Cu) = 1.50 mol CuThen, we can use the heat of fusion to calculate the amount of heat required:1.50 mol Cu * (13.1 kJ/mol) = 19.6 kJTherefore, the correct answer is A) 19.6 kJ.
