Question

the analyst dissolved 15.32 grams of sodium iodide in 150 mLof water. This solution of sodium iodide was reacted with 295 mL ofaqueous 0.155 M lead (II) nitrate to produce a precipitate of lead(II) iodide and aqueaous sodium nitriate. The mass of theprecipotate actually generated by the analyst was 8.262grams. Write and balance the equation for this reaction. (Hint wateris a solvent and will not be either a reactant or product in thisreaction) the analyst dissolved 15.32 grams of sodium iodide in 150 mLof water.
