If 25.00 mL of 0.385 M plumbous nitrate solution and the 20.00 mL of 0.967 M ammonium iodide are combined, determine the numbers of grams of lead (II)iodide could be produced? When aqueous solutions of plumbous nitrate and ammonium iodide are combined, solid lead(II)iodide and the aqueous ammonium nitrate are formed.
