Explanation:
Mass of solute (1) = 300gm × 25/100 = 75 gram
mass of solute (2) = 400 g × 40/100 = 160 g
total mass of solute 75×160= 235 gram
total mass of solution = 300+400= 700 g
% composition by mass of solute = mass of solute / total mass of sol. × 100
= 235/700×100
= 33.57% solute
% composition of mass by solvent = 100 - 33.57

Answer:
Explanation:
Find gram × percentage and divide by total
300×.25 + 150×0.4 / 450
75+60 / 450
135 / 450
30 percent
