The students decide to perform an experiment to test for the presence of lead. The students take a sample of water to the lab and add solid NaI, which will precipitate any lead ions according to the following equation. 2 Nal(aq) + Pb²+ (aq) PbI₂ (s) + 2 Na+ (aq) 0.0184 gram 44% 10:49 If a 2000.0 mL sample of water has a lead ion concentration of 2.00 x 10-5 M and excess NaI is added to the sample, what is the mass of PbI2 collected at the end of the experiment?
