1. Percent Yield

2. Percent yield is the ratio of the actual yield to the theoretical yield (amount that can be made) times 100.
%yield =( 𝑎𝑐𝑡𝑢𝑎𝑙 𝑦𝑖𝑒𝑙𝑑 𝑡ℎ𝑒𝑜𝑟𝑒𝑡𝑖𝑐𝑎𝑙 𝑦𝑖𝑒𝑙𝑑 ) x 100
You will either get the actual yield or the % yield in the problem and will get all the information to find the theoretical yield. Then you can plug them into the equation and solve for what is missing.

3. N2 + 3H2 → 2NH3
If 23.09g N2 reacts with 8.26 g H2 according to the equation below and g NH3 are produced, (a) what is the limiting reactant (b) what is the theoretical yield (c) what mass of the excess reactant remains and (d) what is the % yield of the reaction?
