Question

80 gram of sodium sulphate is dissolve in 120 gram of water find the mass percentage of sodium sulphate in solution

Answer 1

HELLO !!!
Here's Your Answer

>>-------✡--------<<


mass of solute = 80g

mass of solution = mass of sodium sulphate+ mass of water

= 80 + 120

= 200g

mass% = mass of solute / mass of solution × 100

= 80/200 × 100

= 40

so, mass percent of sodium sulphate = 40%
