Expected yield is only 350 dollars
Actual yield = 1220 dollars
% = (Actual yield/expected yield)*100% = (1220/350) *100 % = 348.6%
i.e., the yield is more than 3 times that of expected.
In the case of chemical reactions, it is impossible to get a yield more than 100% . If this happen this mean you may have some impurities in your product and you should purify it. If you use an excess amount of the reactant, may be your product still contains the unreacted reactant. Some products could adsorb water or other used solvent during separation and purification process.

In a chemical reaction, the reactant that limits the amount of product that can be formed is called the limiting reactant (or limiting reagent). The reaction will stop when all of the limiting reactant is consumed. In the sandwich example, bread was our limiting reactant. The reactant or reactants in a chemical reaction that remain when a reaction stops when the limiting reactant is completely consumed are called the excess reactant(s). The excess reactant(s) remain because there is nothing with...

Questions 1. Why is it necessary to write the balanced chemical equation for the reaction before completing any stoichiometry problems? The balanced equation makes it possible to Convert information about a reactant or product to quantitative data, per the Conservation of matter. 2.
