Question

When M1 gram of ice at $-10^{\circ} \mathrm{C}$ (specific heat $=0.5 \mathrm{cal} \mathrm{g}^{-1 \circ} \mathrm{C}^{-1}$ ) is added to $\mathrm{M}_2$ gram of water at $50^{\circ} \mathrm{C}$, finally no ice is left and the water is at $0^{\circ} \mathrm{C}$. The value of latent heat of ice, in $\mathrm{cal} \mathrm{g}^{-1}$ is :

Select the correct option:

A

$\frac{50 M_2}{M_1}-5$

B
