Question

What will be the mass percentage of the solute of a solution with 400g of water and 100g of solute?

Answer 1

Mass of solute = 100 g

Mass of solvent = 400 g

T = m1 / m1 + m2

T = 100 / 100 + 400

T = 100 / 500

T = 0.2

T% = 100 * 0.2

T = 20%

Answer 2

Total Mass of solution= (400+100)g = 500g

Mass of solute = 100g

Therefore ,

Percentage of Solute →

(Mass of solute/ Mass of Solution) × 100%

=( 100/500) × 100%

= 1/5 × 100%

= 20%

Answer→ Percentage of Solute is 20%.
