Post Lab Calculations and Questions 1.) Calculate the theoretical yield of aspirin 2.) Calculate the amount of excess reagent remaining. 3.) Calculate the %-yield Q1.) Draw the structure of aspirin, circle the ester group. Q2.) Salicylic acid will react with methanol (CH3OH), and form methyl salicylate. In this experiment, you will take a measured mass of salicylic acid and add a measured volume of acetic anhydride. You will determine the yield of crystallized aspirin. Then you will test a portion of you synthesized aspirin with FeCl3 solution in order to establish whether salicylic acid behaves as a phenolic alcohol or as a carboxylic acid in ...

The calculations for theoretical yield and percent yield should be shown below the table. Note: _____ was the limiting reagent, since the only other reagent involved in the reaction, sulfuric acid, served as a catalyst. Mass (g) Appearance of Liquid Boiling Pt. ((C) (/Pressure) Theoretical Yield (g) % Yield Methylpentenes Sep 02, 2010 · Aspirin has a GMM of 180 g/mol. Given that I have 2.1g of salicylic acid (.015 moles) and 4.0 mL (.0424 moles) of acetic anhydride how do I calculate the theoretical yield. I am looking for a step by step walkthrough of this where it is explicitly stated how to calculate this. I do not necessarily need the actual number I just really need a refresher on how to do this problem. discussion lab report aspirin synthesis

The mole (abbreviation mol) is the SI unit for the amount of a substance. A mmol (one thousandth of a mol) is a way to talk about a part of a mol. Thus, the conversion factor from mol to mmol is 1,000 mmol in 1 mol. Converting to mmol can be convenient if the number of mol is small. Nov 12, 2020 · Aspirin and Tylenol were synthesized by means of crystallization, recrystallization, and melting point determination. Acetic anhydride and salicylic acid are mixed together, and then acidified by the addition of a few drops of concentrated sulfuric acid, which catalyzed the reaction.

Dec 09, 2008 · Find limiting reagent and write a balanced equation first. It might be a 1:1:1 mole ratio of salicyclic acid and anhydride and ASA. Might be 2:1:2, but I sorta forgot, don't feel like drawing out the long mechanisms, gets kinda "if-y", look up your literature or ask the prof. Convert everything into moles and you'll see which is the limiting reagent, and that number of moles is the theoretical ...

In the banana oil lab we began with isopentyl alcohol + acetic acid isopentyl acetate + Water. In class we started the reaction and observed the scent of the ester forming. Remove the magnetic stirring bar using a magnetic stick. <br> <br> <br> <br> This would have been done relsing. A more inconvenient scenario is if the reagents have a lower boiling point than either the ester product or ... Dec 09, 2008 · Find limiting reagent and write a balanced equation first.

Theoretical yield formula. Using the theoretical yield equation helps you in finding the theoretical yield from the mole of the limiting reagent, assuming 100% efficiency. So, to stop you from wondering how to find theoretical yield, here is the theoretical yield formula: mass of product = molecular weight of product * (moles of limiting reagent in reaction * stoichiometry of product)
