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.
Mass % = Mass of solute / () x 100
(b). Compare the mass % of the two solutions.
Solution made by Ramesh
Mass % = 10 / () x 100
Mass % = 10 / 110 x 100
Mass % = %.
Mass % = 10 / 110 x 100
Mass % = %.
Solution made by Sarika
Mass % = 10 / 100 x 100 = %.
The solution prepared by Sarika has a higher mass % than that prepared by Ramesh.
