Question

if 110 gram of copper sulphate is present in 550 gram of solution calculate the concentration of solution

Answer 1

The concentrate of solution = (mass by solute / mass by solution ) *100

=( 110 /550)*100

= 20%

So, the concentrate of solution is 20%

Answer 2

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

Here, mass of solute (i.e. copper sulphate) = 110g

Mass of solution = 550 g

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

= 20%
so concentration of solution=20%
