Solving for a reactant in solution

One way in which the useful metal copper is produced is by dissolving the mineral azurite, which contains copper(II) carbonate, in concentrated sulfuric acid.
The sulfuric acid reacts with the copper(II) carbonate to produce a blue solution of copper(II) sulfate. Scrap iron is then added to this solution, and pure copper
metal precipitates out because of the following chemical reaction:
Fe(s) + CUSO 4(aq)
Cu(s) + FeSO4(aq)
Suppose an industrial quality-control chemist analyzes a sample from a copper processing plant in the following way. He adds powdered iron to a 100. mL
copper(II) sulfate sample from the plant until no more copper will precipitate. He then washes, dries, and weighs the precipitate, and finds that it has a mass of
92. mg.
Calculate the original concentration of copper(II) sulfate in the sample. Be sure your answer has the correct number of significant digits.

- One way to determine the hardness of a water sample is to precipitate the calcium out of solution as a carbonate. The net ionic reaction for this precipitation is: Ca2+(aq) + CO32-(aq) → CaCO3 (s) A 1.00 L sample of water is drawn from a Phoenix, AZ well and 0.534 g of calcium carbonate is recovered using the above reaction. What was the Ca2+ concentration of the original water sample in ppm? Show your work and include units.
