In the following reaction, 9.7 mL of benzaldehyde was reacted with 3.7 mL of acetone to form 6.41 g of pure dibenzalacetone. Show the calculation for the moles of benzaldehyde, the moles of acetone, the theoretical yield of dibenzalacetone in grams, and the calculation for the % yield of the product (dibenzalacetone). Also indicate which reagent is the limiting reagent.
Molecular weight are as followed Benzaldehyde=106.13g/mol, acetone 58.o8g/mol. dibenzalacetone 234.30g/mol
