Question

To make a saturated solution72g of Copper sulphate is dissolved in 400g of water at 300C. Find its concentration at the same temperature.

Answer 1

◆ Answer- 26.47 %

◆ Explanation-

# Given-

m = 72 g

M = 200 g

T = 20 °C

# Solution-

Concentration of the solution is given by-

C = mass(solute) / mass(solution) × 100

C = m / (m+M) × 100

C = 72 / (72+200) × 100

C = 72 / 272 × 100

C = 26.47 %

Concentration of the solution is 26.47 % .
