{tex}\mathop {at\,0^\circ C}\limits^{ice} \to \mathop {at\,0^\circ C}\limits^{water} \to \mathop {at\,6^\circ C}\limits^{water} {/tex}

At equilibrium, heat released by 100gm of water = heat absorbed by 100gm of ice i.e.m₁c₁ (80 - 6) = m₂ L + m₂c₁(6 - 0)[c₁, m₁, m₂ and L are specific heat of water, mass of water, mass of ice and latent heat of fusion of ice respectively.)
{tex}\therefore{/tex}100 × 1 × 74 = 100 L + 100 × 1 × 6

{tex}\Rightarrow{/tex} L = (1 × 74) -6
{tex}\Rightarrow{/tex}L = 68 cal/gm

This is the required value of latent heat of fusion of ice.
