need help please with (detailed % yield calculation and limiting reagent) not sure if I did it right please check    The Aldol condensation Apparatus required: Erlenmeyer flask, pipette, beakers, stirring rod, warm bath, weighing balance. Chemicals required: Sodium hydroxide (NaOH), ethanol (EtOH), anisaldehyde, acetone, and sodium bicarbonate. Procedure: 1. 7ml of 10% sodium hydroxide was added to the Erlenmeyer flask then 12ml of 95% ethanol was also added to the same flask. 2. In the ethanolic sodium hydroxide solution, 2ml of anisaldehyde was added with the help of the pipette. 3. Stirred the solution well and then 0.5ml of acetone was also added to this flask. 4. Allowed the reaction to cool at room temperature for 30 minutes. 5. Cooled the solution in the ice water bath. 6. Precipitates were filtered by vacuum filtration using a Hirsch funnel. 7. Precipitates were washed with ice-cold water. 8. Approximately 5ml of 95% ethanol was added and dissolved. 9. Allowed the flask to crystalize at room temperature before cooling in an ice bath. 10. Added to ice bath for recrystallization. 11. Collected the product by vacuum filtration and weighed. 12. Melting point of the product was measured.
