In an experiment to remove lead from a sample of water, a student added potassium iodide to a solution of lead nitrate and obtained a precipitate of PbI2. At the end of the reaction, the student isolated 0.525 grams of PbI2. Assuming a 100% yield, calculate the following: a. The amount in grams of Pb(NO3)2 in the sample remediated by the student; and b. The minimum amount in grams of KI that would be required to remediate this solution. Show all calculations in a neat and organized fashion. If you need it, the breakdown of the steps for this calculation are below
