(C) The molar mass of sucrose $(C_{12}H_{22}O_{11})$ is $(12 \times 12) + (22 \times 1) + (11 \times 16) = 144 + 22 + 176 = 342 \ g/mol$. Number of moles of sucrose = $\frac{\text{Given mass}}{\text{Molar mass}} = \frac{34.2 \ g}{342 \ g/mol} = 0.1 \ mol$. Since $1 \ mol$ of $C_{12}H_{22}O_{11}$ contains $12 \ mol$ of carbon atoms,Number of moles of carbon atoms = $12 \times 0.1 \ mol = 1.2 \ mol$.
