In one experiment, 22.9841 grams of 75.25% pure Pb(NO3)2 (pure Pb(NO3)2 has amolar mass of 331.2 grams) was mixed with 51.2354 grams of 81.21% pure CsI (pure CsIhas a molar mass of 259.80992 grams):2CsI(aq) + Pb(NO3)2(aq) 2CsNO3(aq) + PbI2(s). After the reaction, 10.4025 grams of PbI2(s) (molar mass 461.0 grams) were collected. What is the percent yield of the reaction?
