Question

A solution of glucose in water is labelled as 10% w/w, what would be the molality and mole fraction of each component in the solution? If the density of solution is 1.2 g mL -1 , then what shall be the molarity of the solution?

Answer 1

Molality= 10/180 x 1000/90 = 0.617 The mole fraction of glucose =10/180 / 10/180 + 90/18 = 0.0108 Mole fraction of water = 1- 0.0108= 0.98 Molarity= 10 /180 x 1000/ 100/1.2= 0.66
