Calculate the percentage composition in terms of mass of solution obtained by mixing `300 g` of a `25%` and `400 g` of a `40%` solution by mass. |

Answer» Correct Answer - `31.9%` Mass of `25% sol A =(25)/(100)xx300=75g` mass of `40% sol B (40)/(100)xx400=160g` `%` composition of `A` `=(75xx100)/(75+160)=(75xx100)/(235)=31.9%` `%` composition of `B=100-31.9 = 68.1%` |
