Question

during an experiment thestudents were asked to prepare 10 % (mass by mass )solution of sugar in water .ramesh dissolved 10 gram of sugar in 100 gram of water while sarika prepared it by dissolving 10 gram of sugar in water to make 100 gram of solution.

a) are the two solution of same concentration?

b) compare the mass precent of two solution.

Answer 1

a) No, the two solutions have different concentrations

b) mass % of solution prepared by Ramesh = (10/110) x 100 = 9.09%

mass % of solution prepared by Sarika = (10/100) x 100 = 10 %
