A \(\text{solid}\) initially at \(20\text{ }^\circ C\) is heated. The graph given above shows variation in temperature with the amount of heat energy supplied to it. Now, if the specific heat capacity of solid is \(2\text{ J}{g}^{-1}{\text{ }^\circ C}^{-1},\) calculate

(i) the mass of the solid, and

(ii) the specific latent heat of fusion of solid.

Submit your answer as the sum of (i) (in grams) and (ii) (in \(\text{ J/g}\)).
