2.When calculating the yield in a stoichiometry problem, wegenerally follow four steps after balancing the chemical equation: 1)convert all given masses to moles, using conversion factors createdfrom the molar masses; 2) convert moles of limiting reactant to molesof product, using conversion factors created from their stoichiometriccoefficients in the chemical equation; 3) calculate the theoretical yieldof the product by converting moles of product to mass of product, usingconversion factors created from its molar mass; 4) calculate the yield ofthe product from its experimentally obtained mass and its theoreticalyield.If a scientist weighed 0.68 g of the reactant Na2CO3 for the reactionbelow, how many moles of Na2CO3 would he have?

Lead(II) carbonate, also called "white lead," was formerly used as a pigment in white paints. However, because of its toxicity, lead can no longer be used in paints intended for residential homes. Lead(II) carbonate is prepared industrially by reaction of aqueous lead(II) acetate with carbon dioxide gas. The unbalanced equation is Pb(C,H3 O2)2 (ag) + H2O(1) + CO2(9) → PbCO3(s) + HC,H3 O2 (ag) Suppose an aqueous solution containing 1.20 g of lead(II) acetate is treated with 5.85 g of carbon dioxide.
