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