The ΔH fusion used to calculate the energy released when a mass of liquid freezes by using the formula Grams liquid x mol/g x ΔH fusion.
What is enthalpy?
Chnage in enthalpy (ΔH) of any reaction gives idea about the amount of total heat released or absorbed in any chemical reaction.
Heat of formation or enthalpy is given for any one mole of substance.
And it will be calculated for moles of gases as, so for this first mass will be converted into moles as-
n = W/M, where
W = given mass in grams
M = molar mass in g/mol
and then multiply the given moles by the enthalpy of formation of one mole.
Hence, Grams liquid x mol/g x ΔH fusion is used.
