(C) Since $MSO_4 \cdot 7H_2O$ is isomorphous with $ZnSO_4 \cdot 7H_2O$,the molar mass of $MSO_4 \cdot 7H_2O$ is $M + 32 + (4 \times 16) + 7 \times (2 \times 1 + 16) = M + 32 + 64 + 126 = M + 222 \, g/mol$.The percentage of metal $M$ is given by: $\frac{M}{M + 222} \times 100 = 9.87$.$100M = 9.87M + 222 \times 9.87$.$100M - 9.87M = 2191.14$.$90.13M = 2191.14$.$M = \frac{2191.14}{90.13} \approx 24.3 \, g/mol$.
