If a total of 780 joules of energy is lost by
ankoles [38]

If a total of 780 joules of energy is lost by  25.0 grams of this substance, the heat of fusion is 31.2 J/g

The energy lost, H  =  780 Joules

Mass of the substance, m = 25.0 grams

The Energy lost is the product of mass and the heat of fusion

The heat of fusion, c, is calculated using the equation below:

H   =  mc

Substitute H = 780 Joules and m = 25.0 grams into the equation

H   =  mc

780   =   25c

Divide both sides by 25

\frac{780}{25} = \frac{25c}{25}  \\c = 31.2 Joules/g

The heat of fusion of the substance is 31.2 J/g
