Solution

Total amount of solutepresent in the mixture is given by,
= 75 + 160
= 235 g
Total amount ofsolution = 300 + 400 = 700 g
Therefore, masspercentage (w/w) of the solute in the resulting solution,
= 33.57%
And, mass percentage(w/w) of the solvent in the resulting solution,
= (100 − 33.57)%
= 66.43%
