A solution is obtained by mixing 200 g of 30% and 300 g of 20% solution by weight. What is the percentage of solute in the final solution
A
50%
B
28%
C
64%
D
24%
Answer
24%
Explanation
Solution
Solute in 200 g of 30% solution = 60 g
Solute in 300 g of 20% solution = 60 g
Total grams of solute = 120 g
Total grams of solution = 200+300 =500 g
% of solute in the final solution =500120×100=24%
