Use the following atomic weights and quantities to calculate the overall % yield of diphenylacetylene. Remember that your yield must be based on the limiting reagent, and that grams must be converted to moles. For problems not involving a one to one stoichiometry it may be easier to calculate the theoretical yield in grams from both reagents to determine which is truly the limiting reagent. Filling out most of the chart will help. Give...
