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

(b) Compare the mass % of the two solutions.

Question

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

(b) Compare the mass % of the two solutions.

Philoid · Accepted Answer

(a) No, the two solutions do not have the same concentration.

(b) Mass percentage of solution prepared by Ramesh =

Mass percentage of solution prepared by Sarika =
The solution prepared by Ramesh has less percentage (9.09%) by mass than that of Sarika (10%). Thus, the solution prepared by Sarika has a higher mass % than that prepared by Ramesh.
