I can't solve that. But it is a homework from chemistry.
We mix up water and sugar with analogy 4:1 correlatively, when result solution D, which has density 1.15 g/ml. Find:
a. the amount of sugar, which is included in 500 g of solution D
b. the contents % w/w and % w/v of solution D
Please answer me soon.
I hope you understand the problem.
