Question

I'm trying to figure out the Theoretical yield and % yield. We had the Aldol Condensation reaction in which we started with 0.1412 g of 4-Chlorobenzaldehyde (MW of 140.57 and Density of 1.12) We added .12 mL of Acetophenone + .80 mL of 95% Ethanol + .10 mL of NaOH. We added some water and filtered it. To crystallize the Chalcone, we purified with a 50:50 mix of Ethanol/Methanol. Our Final mass of 4-Chlorochalcone was .2761 grams

Answer 1

volume of aceto phenone = 0.12 mL

mass = 0.12 mL x 1.028 g/mL

= 0.1233 gr
