A 100. 0 mL volume of a 0. 10 M stock solution of Cu²+ is to be prepared using CuSO4*5H2O (molar mass = 249. 68 g/mol) ².
a) How many grams of CuSO4*5H2O must be measured for the preparation?
b) Describe the procedure for the preparation of the solution using 0. 01 M HNO3 as a diluent, starting with conc (16 M) HNO3.
c) A 2. 0 mL pipet transfers the Cu²+ stock solution to a 25. 0 mL volumetric flask, Which is then diluted to the mark of the volumetric flask with 0. 01 M HNO3. What is the molar concentration of the diluted Cu²+ solution?
