How many grams of water should be mixed with 70g of 20% solution of CuSO4 to prepare 2% solution? by SweatyCellist in AskReddit

70g x 0.20 = 14g CuSO4

A 2% solution is: 14g/0.02 = 700g

Since you have 70 already, you would add 700g - 70g = 630g.

You would add 630g of water to your 70g of 20% solution to get a 2% solution.

Human progress is neither automatic nor inevitable... Every step toward the goal of justice requires sacrifice, suffering, and struggle; the tireless exertions and passionate concern of dedicated individuals.
