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.

During an experiment, two students were asked to prepare a 10% (Mass/mass) solution of salt in water. Rahul dissolved 10 g of salt in 100 g of water while Priya prepared it by dissolving 10 g of salt in water to make 100 g of solution. (a) Do the two solutions have same concentration ? (b) Calculate mass/mass percentage in each case. (c ) Whose measurements are correct for the experiment ?

(a) Two students Ramesh and Alka were required to prepare 10 percent (mass/mass) solution chloride in water. For that, Ramesh dissolved 10 g of the salt in 100g of water while Alka dissolved 10g of the salt in water to make 100g of the solution. Which out of the two prepared the correct solution ? (b) You are given a solution of a substance 'A'. How will you test whether it is saturated or unsaturated with respect to 'A' at a given temperature ?
