A solution is obtained by mixing 300 g of 25% solution and 400 g of 40% solution by mus. Calculate the moss per centage of the resulting solution.

Text Solution

Verified by Experts

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%.
