What is the concentration of a copper sulfate solution if 40.0 mL of the solution requires 1350 coulombs of charge to fully oxidize all the copper ions present, using a coulometric titration method? The solution was prepared by dissolving a sample of copper sulfate pentahydrate in water and diluting it to a final volume of 500 mL. Given the molar mass of copper sulfate pentahydrate and the total charge required to oxidize one mole of copper ions.
