The molar mass of sugar  C_{12}H_{22}O_{11} is:

= (12\times12)+ (1\times 22)+(11\times16) = 342g\ mol^{-1}.

The number of moles of sugar in 20g of sugar will be:

= \frac{20}{342} = 0.0585\ mole

and given the volume of the solution after dissolving enough water is 2L.

 Molar\ concentration = \frac{Moles\ of\ solute}{Volume\ of\ solution\ in\ 1L}

= \frac{0.0585mol}{2L} = 0.0293mol\ L^{-1} = 0.0293\ M
