Question

During an experiment the students were asked to prepare a 10% 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. Compare the mass % of the two solutions.

Answer 1

Solution made by Ramesh
Mass $=\left(\frac{10}{10+100}\right)100=\frac{10}{110}\times 100=9.09$%
Solution made by Sarika
Mass $=\frac{10}{100}\times 100=10$%
