Question

If 110g of copper sulphate is present in 550g of solution,calculate the concentration of solution.

Answer 1

%concentration=solute /solution ×100
=(110/550×100)%
=(1/5×100)%
=(20)%

Answer 2

SOLUTIONS:

Here,

Mass of solute (copper sulphate) = 110 g

Mass of solution = 550 g

Now, we know that :

» Concentration of solution = Mass of solute / Mass of solution × 100

⇒ 110/550 × 100

⇒ 11000/550

⇒ 100/5

⇒ 20 per cent.

Thus, the concentration of this copper sulphate (CuSO₄) solution is 20%.
