Question

the heat of fusion of aluminum is 95 cal/g. calculate how many grams of aluminum(already at its melting point) could be melted with 1,265,730 cal of energy (round your answer to two decimal places)

Answer 1

Mass of aluminium : 13323.47 g

Further explanation

Given

Lf=latent heat of fusion of Al = 95 cal/g

Q = 1,265,730 cal

Required

mass of Aluminium

Solution

The heat to change the phase can be formulated :

Q = m.Lf (melting/freezing)

Input the value

1,265,730 cal = m . 95 cal/g

m = 1,265,730 cal : 95 cal/g

m = 13323.47 g
