Question:

heat of fusion of aluminum?

The heat of fusion of aluminum is 3.95kj/g. What is the molar heat of fusion of aluminum? What quantity of energy is needed to melt 10.0g of aluminum? What quantity of energy is required to melt 10.0 mol of aluminum? Three questions i need help with can someone show me step by step please so i can get it thank you a bunch

Answer:

Heat Of Fusion Of Aluminum
Two multiplications will solve your problem: Q1 = m1 x Del(Hf) Q1 = (14.5 x 0.395) kJ = 5.73 kJ Q2 = n2 x Del(Hmol) Q2 = (14.5 x 107) kJ ~ 1,552 kJ
This is a specific heat problem. The specific heat of Aluminum is 0.902J/(g*C). Use the units to help you 'drive' the calculation, ie. set up the problem so that g and C cancel and you are left with J.

using molar mass, What is the molar heat of fusion of aluminum? 3.95 g/mole 26.98 g/mol = your first answer the molar heat of fusion is 107 kJ/mol ======================================... What quantity of energy is needed to melt 10.0g of aluminum? 10.0 g Al 3.95 kJ/g = your second answer 39.5 kJ ======================================... What quantity of energy is required to melt 10.0 mol of aluminum? 10.0 moles 107 kJ/mol = your last answer 1,070 kJ
