Question

I have a 0.00156 M solution of CuSO4*5H2O in water (from 0.0398 g of CuSO4*5H20 in 100 mL of water). How would I calculate the ppm of Cu of that solution from that information?
Now if I were to find ppm of Cu in different aliquots of this stock solution (5 mL, 10 mL, etc.) how would I go about that?

Answer 1

I gave you detailed instructions for this problem yesterday (late yesterday).
