Question
determine the theoretical yield and percent yield for this reaction Place 2 ml of nitrating reagent into a 5-mL vial with a spin vane and cap vial. 2. Cool reaction vial in an ice-salt water (10% sodium chloride) bath for 10 minutes with slow stirring. 3. Place the acetanilide from the first reaction into reaction vial with nitrating reagent. 4. PLACE CAP ON VIAL BUT DO NOT TIGHTEN CAP ON VIAL. 5. Stir reaction mixture for 45 minutes in ice-salt water bath IN THE HOOD. 6. Maintain ice in the ice-salt water mixture during the 45-minute reaction period. Isolation and Purification of Product 1. Fill a 100-mL beaker about two-thirds full with an ice-water mixture with gentle stirring for 3 minutes. 2. Add 25 mL of cold water from the ice-water mixture into a 50-mL Erlenmeyer flask. 3. Pour reaction mixture in 5-mL vial into the cold water in the 50-mL flask. 4. Rinse 5-mL vial with 2 mL of cold water and add to 50-mL flask. Repeat. 5. Stir cold-water solution with glass rod and break up any large particles.Explanation / Answer
Theoritical yield = (number of moles of reacting molecule) x product molecular mass.
You have not mentioned with how many grams (or mL) of the reactant(ACETANILIDE) were used. Convert the grams into moles by dividing number of grams (reactant taken) by molecular mass.
% Yield = [(Product obtained in grams ) / (theroritical yield in grams)] x 100.
