A solution is obtained by mixing 300 g of 25% solution and 400 g of 40% solution by mass. Calculate tile mass percentage of the resulting solution.
300 g of 25% solution contains solute = 75g
400g of 40% solution contains solute = 160 g
Total mass of solute = 160 + 75 = 235 g
Total mass oÍ’ solution = 300 + 400 = 700 g
% of solute in the final solution = \(\frac{235}{700}\) x 100 = 33.5%
% of water in the finaI solution = 100 – 33.5 = 66.5%

300 g of 25% solutions contains solute = 75 g
400 g of 40% solution contains solute = 160 g.
Total solute = 160 + 75 = 235 g
Total solution=300 + 400 = 700 g
% of solute in final solution = \(\frac{235}{700}\) × 100 = 33.5%
% of water in the final solution = 100 – 33.5 = 66.5%
Total amount of solute present in the mixture is given by
300×25/100+400×40/100
, = 75 + 160
= 235 g
Total amount of solution = 300 + 400 = 700 g
235/700×100%
Therefore, mass percentage (w/w) of the solute in the resulting solution,
= 33.57%
And, mass percentage (w/w) of the solvent in the resulting solution,
= (100 − 33.57)%
= 66.43%
