How do I calculate the limiting reagent and percent yield for creating tetraphenylcyclopentadienone in the lab from by aldol condensation. I Benzil (0.15 g) reacted with 1,3- Diphenylacetone (0.15 g). Later, 1..2 ml of ethanol and 15 drops of 2.0 M KOH was added to the mix. Molar mass of benzil = 210. 23 Molar mass of 1,3 Diphenylacetone = 210. 28 Molar mass of product = 382.5 I ended up with 0.30 g of product. How do I calculate the limiting reactant and the % yield? I attempted the problem and got more than 100% so, I must have calculated something wrong. Solution Limiting reagent could be either Benzil or 1,3-diphenyl acetone, because they were reacted in equal equivalents and both of the must be completed according to the reaction kinetics (0.714 mmol and 0.714 mmol each). Thearetical yeild should be 0.272 g. you have got more than this! This seems the human Error!! You might not measured well either of the reagents or products. Good luck next time. .
