(C) The molarity $(M)$ is defined as the number of moles of solute per liter of solution: $M = \frac{n}{V(L)}$.Given $M = 0.1 \ M$ and $V = 2 \ L$,the number of moles $(n)$ is $n = M 	imes V = 0.1 	imes 2 = 0.2 \ mol$.The molar mass of sugar $(C_{12}H_{22}O_{11})$ is $(12 	imes 12) + (22 	imes 1) + (11 	imes 16) = 144 + 22 + 176 = 342 \ g/mol$.The mass required is $mass = n 	imes 	ext{molar mass} = 0.2 \ mol 	imes 342 \ g/mol = 68.4 \ g$.

The amount of sugar $(C_{12}H_{22}O_{11})$ required to prepare $2 \ L$ of its $0.1 \ M$ aqueous solution is ............... $g$.
