Answer 1

Answer:

hope it might help..........

Explanation:

Mass percent = mass of solute / mass of solution. Here mass of solution = 250g. Mass of solute = X. Mass percent = 40. Hence 40% = X/250. Therefore X = 100g. Hence amount of solute needed to make 250g of 40% solution is 100g. As we know mass of solution = mass of solute + mass of solvent, Therefore mass of solute = 250g – 100g.

Hence the mass of solute = 150g
