A solution is obtained by mixing 300 g of 25% solution and 400 g of 40% solution by mass. Calculate the mass percentage of the resulting solution.
According to question,
300g of 25% solution contains solute = (300 x 25) / 100 = 75g
&
400g of 40% solution contains solute = (400 x 40) / 100 = 160g
Total solute = 75 + 160 = 235g
As given in the question, total solution =300 + 400 = 700g
Percentage of solute in the final solution = (235 x100) / 700 = 33.57%
Percentage of water in the final solution = 100 - 33.5 = 65.43%

Thnx sir
But finally percentage is 64.5%
Please correct that Percentage of H2O in final solution is 66.5 % not 65.5 %
Please correct that Percentage of H2O in final solution is 66.5 % not 65.5 %
Thanks
thnx sir
Thanks sir for this answer, this answer will help me a lot
Thanks
