Calculate the Theoretical Yield to determine the % yield in a chemical reaction

# data[].attributes.attachment_link.description
Determine the Theoretical yield (the maximum amount of product that can be produced when 2 values for 2 reactants are given). Then determine the % yield, assuming the actual yield (the amount of product actually weighed out when the reaction is carried out in the lab) is given.
