Question

30 gram of glucose and 20 gram common salt is dissolved in 500 gram of water to make a solution. calculate the concentration of glucose and common salt in terms of mass by percentage of solution.

Answer 1

Mass of glucose - 30 grams

Mass of common salt - 20 grams

Mass of water - 500 grams

Mass of solution - 500+20+30 = 550

Concentration of glucose - (mass of solute * 100) / mass of solution

(30*100)/550

=5.45%

Concentration of common salt - (mass of solute * 100) / mass of solution

(20*100)/550

=3.64%
