A solution is prepared by dissolving 11g glucose in 200 cm3 water at 300c. What is the mass percentage of glucose in solution ? The density of water at 300c is 0.996g /cm3?
Dear student!
Here, mass of water(solvent) = volume x density = 200 x 0.996 = 199.2 gm
Mass of solute (glucose) = 11 gm
So, mass of solution = 199.2 + 11 = 210.2
Mass %age of solute =( mass of solute / mass of solution) x 100
So, mass %age of glucose = (11/210.2) x 100 = 5.2 %
