A chemist has a supply of supersaturated CuSO4 solution that contains 230.0grams per litre of water. The chemist also has another supply of copper sulphate solution with a concentration of 150.0 grams per litre. What quantities of each copper sulphate solution should be mixed together to make 2L of a 200.0grams per litre solution of Copper Sulphate?

Answer 1

This can be done??
If you use 2L of the weaker solution of 150g/L and zero L of the more concentrated solution, then you have 300g/2L and that is too concentrated.

Answer 2

I see a problem below that has been answered by Mathmate that isn't the same problem as this one. This one doesn't allow water to be added and both of the solutions available are more concentrated than the final desired one. I don't think this one is possible.
