3 g of dry substance is present in 100 g of solution.
By unitary method:
The weight of dry substance in 1 g of solution =
The weight of dry substance in 150 g of solution =
Let the weight of solution be w.
8 % solution contains 8 g dry substance in 100 g.
We have to find the weight of the solution(w) which contains 4.5 g of dry substance.
