Scrap iron is then added to this solution, and pure copper metal precipltates out because of the following chemical reaction: Suppose an Industrial quality control chemist analyzes a sample from a copper processing plant In the following way. He adds powdered Iron to a 400. mL coppen) sulfate sample from the plant until no more coppr will precipitate. He then washes, dries, and weighs the preripitate, and finds that it has a mass 133, Ing Caloulate the original concentration of copp) sulfate in the sample. Bes your answer has the correct number of significant digits. Check :30 PM rP ^: 11/30/2017 LEKS-Learn

Explanation / Answer

NO of mol of Cu = 0.133/63.55 = 0.0021 mol

NO of mol of CuSO4 = 0.0021 mol

molarity of CuSo4 = n*1000/v

                  = 0.0021*(1000/400)

                  = 0.00525 M
