Add 20ml of Lead Nitrate into beaker


Pour contents of beaker into flask

save solid in watch glass and record weight of solid: 19.11g

Queation: Calculate % yield= (actual yield/predicted yield ) x 100

=(actual yield/((20ml/1000ml/literxGMW of Pbl2))x100%

=(actual yield/(.02x461.009))x100%

=(actual yield/9.22x100%

= ????
