Question

During an experiment student 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 solution. ANSWER the following 5 Marks Are the two solutions of the same concentrations? Compare the mass% of two solutions. Define Solubility. Which type of solution causes Precipitation?​

Answer 1

Answer:

Mass % = Mass of solute Mass of solute + Mass of solvent ×100

Solution made by Ramesh

Mass % = 10/ 100 +10 x 100

Mass % = 10 /110 x100

Mass % = 9.09%

Solution made by Sarika

Mass % = 10 /10 ×100

Mass % = 10%

The solution prepared by Sarika has a higher mass % than that prepared by Ramesh.
