• # question_answer How many grams of ice at $0{}^\circ C$ can be melted by the addition of 500 J of heat? (The molar heat of fusion for ice is$6.02\,\text{kJ}\,\text{mo}{{\text{l}}^{-1}}$) A)  0.0831 g                    B)  1.50 gC)  3.01 g                        D)  12.0 g

6020 J is required to melt 18 g of ice at $0{}^\circ C$. 1 J would melt $=\frac{18}{6020}g$of ice at $0{{\,}^{o}}C$             $\approx 3\times {{10}^{-3}}g$ 500 J would melt $=500\times 3\times {{10}^{-3}}g$of ice at $0{{\,}^{o}}C.$ Answer = 1.5 g. Hence, the correct option is [b].
