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?
Correct answer
24
Step-by-step 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 = Wt. of solute Wt. of solution × 100 % of solute in the final solution = 120 500 × 100 = 24 %
