2. Bobby and Jane dissolve 26.8 g of solid potassium iodide (Kl) in water, then pour the solution into an excess of concentrated lead (LI) nitrate. Jane carefully filters the
resulting yellow precipitate from the solution and dries the solid overnight. The
following day, Bobby finds the mass of the precipitate (which he knows to be Pbly) to
be 34.8 g. What is the percent yield of Pblz in Bobby and Jane's reaction?
Kl =165.99g/mol
Pbl2 = 461.01g/mol
2Kl + Pb(NO3)2 – 2KNO3 + Pblz
