a) If the maximum % Cu in the sample could be no more than the % Cu in pure CuCl2, calculate the maximun possible mass of Cu in the sample.

b) If you needed to make up a total volume of 100ml of the 10% ammonium thiocyanate solution, give a detailed description of how you would make up this solution in the lab including both the calculations and the lab procedure. NH4SCN is a solid

c) Assuming the maximum amount of Cu in the sample (as calculated in a), calculate the volume of the ammonium thiocyanate solution you would need to add with a 10% excess. Assume an ammonium thiocyanate solution density of 1.00g/ml

d) Calculate the % Cu in the sample given in the problem
