During an experiment the students were asked to prepare a `10%` (mass/mass) solution of sugar in water. Ramesh dissolved 10 g of sugar in 100 g of water while Sarika prepared it by dissolving 10g of sugar in water to make 100 g of the solution.
(a) Are the two solutions of the same concentration?
(b) Compare the mass % of the two solutions.

Text Solution

Verified by Experts

(a) No, the two solutions have different concentrations.
(b) Mass % of solution prepared by Ramesh = `("Mass of sugar")/("Mass of solution")xx 100`
`=(10)/((10 + 100)) xx 100 = (10)/(110) xx 100 = 9.09%`
Mass % of solution prepared by Sarika = `("Mass of sugar")/("Mass of solution")xx 100 = (10)/(100) xx 100 = 10.0%`
