What is the concentration of sugar ($C_{12}H_{22}O_{11}$) in mol $L^{–1}$ if its 20 g are dissolved in enough water to make a final volume up to 2 L?

Gram molar mass of sugar ($C_{12} H_{22} O_{11}$) = 342g
$\Rightarrow \large\frac{20g/342g}{2L}=\frac{0.0585mol}{2L}$
$\Rightarrow 0.02925molL^{-1}$
Molar concentration of sugar = 0.02925 mol $L^{–1}$
