Question

During the experiment the student wete prepare: 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 solution.a) are the two solution of the same concentration? b) compre the mass % of the two solution

Answer 1

Hello Mate!

Case 1 ) Mass of solute = 10g
Mass of solvent = 100g
Mass by mass % = 10%

Case 2 ) Mass by solute = 10g
Mass of solution = 100g
Mass of solvent = 100g - 10g
= 90g

Concentration in first solution = 10% [ Given ]

Concentration in second soluton =

M of Solute / M of Solvent × 100 = 10 / 90 × 100

= 100 / 9 % or 11.11%

a. No concentration of two solution is different. One is 10% and another is 11.11%

b. Mass% of solution in case 1 is 10%, mass% of solution on case 2 is 11.11%.

Hence, on comparing we get that mass% of case 2 is ( 11.11 - 10 ) 1.11% greater than that of case 2.

Have great future ahead!
