Give brief answers to the following question:
During an experiment the students were asked to prepare a 15% (Mass/Mass) solution of sugar in water. Ramesh dissolved 15 g of sugar in 100g of water while Sarika prepared it by dissolving 15 g of sugar in water to make 100 g of the solution.
a. Are the two solutions of the same concentration.
Mass % = Mass of solute / () x 100
b. Compare the mass % of the two solutions.
Solution made by Ramesh
Mass % = 15 / () x 100
Mass % = %.
Mass % = %.
Solution made by Sarika
Mass % = 15 / 100 x 100 = %.
The solution prepared by Sarika has a higher mass % than that prepared by Ramesh.
