(C) Given that moles of $SO_2$ = moles of $CH_4$. The molar mass of $SO_2$ is $64 \, g/mol$ and the molar mass of $CH_4$ is $16 \, g/mol$. Using the formula $\text{moles} = \frac{\text{mass}}{\text{molar mass}}$,we have: $\frac{1.24}{64} = \frac{W}{16}$ $W = \frac{1.24 \times 16}{64}$ $W = \frac{1.24}{4} = 0.31 \, g$.
