If 1 10g of CuSO4 is present in 550g of solution. The concentration of solution of
the solution will be
i) 204
ii) 21%
ii) 19%
iv) None of the above​

Answer 1

Answer:

Here ,Mass of solute (copper sulphate ) =110 g

And ,we know that :

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

=110/550×100

=100/5= 20%

=20per cent (or 20 % )

Thus , the concentration of this copper sulphate solution is 20 per cent (or it is 20% copper sulphate solution ),.

Explanation:

Thus , the concentration of this copper sulphate solution is 20 per cent (or it is 20% copper sulphate solution )
