Answer» Solution :MASS of solute in solution - I = `(25)/(100 ) XX 300 ` g = 75 g Mass of solute in solution - II = `(40)/(100) xx 400 ` g 160 g Total mass of solute (I + II) = 75 + 160 = 235 g Total mass of solution = 300 + 400 = 700 g mass percentage of solute in final solution = `(235)/(70) xx 100 = 33.57%` mass percentage of soluent in final solution 100 - 33.57 = 66.43%. |
