A 100.0-mL of a 0.10M stock solution of Cu^2+ is to be prepared using CuSo4x5H2O (mm=249.68)
a. How many grams of CuSO4x5H2O must be measured for the preparation?
b. Describe the procedure for the preparation of the solution using 0.01 MHNO3 as a diluent, starting with conc (16M)HNO3
c. A 2.0-mL pipet transfers the Cu^2+ stock solution to a 25.0-mL volumetric flask, which is then diluted to the mark of the volumetric flask with a 0.01 M HNO3-. WHat is the molar concentration of the diluted Cu^2+ solution?
