Question

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

Answer 1

Mass by mass percentage of a solution = [(Mass of solute) / (Mass of solution)] X 100

Here, mass of solute ( cuSo4) = 110g

Mass of solution = 550 g

Therefore mass by mass percentage of solution = (110 X 100) / 550

= 20%

Hence, the concentration of the solution is 20%. 

Answer 2

Hi friend,

The concentration of solution is 20% .

Explanation :-

The mass by mass % is given as follows:-

Mass by mass % of a solution =

[ ( mass of solute / ( mass of solution ) ] × 100

Here, mass of solute is 110 g

So, the mass of solution is 550 g

Therefore , mass by mass % of solution =

( 110 × 100 ) / 550 g

= 20 % ( proved )
