1.11 What is the concentration of sugar (C12H22O11) in mol L–1 if its 20 g are dissolved in enough water to make a final volume up to 2L?

Molarity (M) of a solution is given by,

= Number of moles of soluteVolume of solution in liters 
= Mass of sugar/molar mass of sugar2L
= 20g/12×12 + 1 × 22 + 11 × 16g2L
= 20g/342g2L
= 0.0585 mol2L

= 0.02925 mol/L
 Molar concentration of sugar = 0.02925 mol/L
