For a research project, a student decided to test the effect of the lead(II) ion (Pb²*) on the ability of salmon eggs to hatch. This ion was obtainable from the water-soluble salt, lead(1I) nitrate, Pb(NO3)2, which the student decided to make by the following reaction. (The desired product was to be isolated by the slow evaporation of the water.) PbO(s) + 2HNO3(aq) → Pb(NO3)2(aq) + H2O Losses of product for various reasons were expected, and a yield of 83.6% was expected. In order to have 4.70 g of product at this yield, how many grams of PbO should be taken? (Assume that sufficient nitric acid, HNO3, would be used.) g PbO

Question
For a research project, a student decided to test the effect of the lead(II) ion (Pb²+) on the ability of salmon eggs to hatch. This ion was obtainable from the water-soluble salt, lead(II) nitrate, Pb(NO3)2, which the student decided to make by the following reaction. (The desired product was to be isolated by the slow evaporation of the water.) PbO(s) + 2HNO3(aq) → Pb(NO3)2(aq) + H2O Losses of product for various reasons were expected, and a yield of 83.6% was expected. In order to have 4.70 g of product at this yield, how many grams of PbO should be taken? (Assume that sufficient nitric acid, HNO3, would be used.) i g PbO
