The molar enthalpy of fusion for water is 6.008 kj/mol. what quantity of energy is released when 253 g of liquid water freezes?

84400 Joules

Explanation:

Molar enthalpy of fusion for water = 6.008 kJ/mol

Molar heat of fusion is the energy required to convert 1 mole of solid to 1 mole of liquid.

1 mole of liquid water on freezing releases energy = 6.008 kJ

Thus 14.06 moles of liquid water on freezing releases energy =

Thus 84400 Joules of energy is released when 253 g of liquid water freezes.
