## Question:

When 5.00 g of copper reacts with excess silver nitrate, silver metal and copper nitrate are produced. What is the theoretical yield of silver in this reaction?

## Stoichiometry:

The area of study in chemistry which is concerned with the quantities of chemical substances produced and required in a chemical reaction. The stoichiometric coefficients of the balanced chemical equation allow the determination of the products produced or reactants required.

As with all calculations in stoichiometry, we must establish the balanced chemical equation for the reaction.

{eq}Cu(s)~+~2~AgNO_3(aq)~\to~2~Ag(s)~+~Cu(NO_3)_2(aq) {/eq}

We can determine the theoretical yield using the molar mass of copper, silver and the stoichiometric coefficients from the balanced chemical equation.

{eq}5.00~g~Cu\times\frac{1~mol~Cu}{63.54~g}\times\frac{2~mol~Ag}{1~mol~Cu}\times\frac{107.8~g}{1~mol~Ag}~=~17.0~g~Ag {/eq}

Therefore, the theoretical yield of Ag is 17.0 g.
