[PDF] Aspirin synthesis from salicylic acid.

Calculating Percent Yield

Example: 5g of aspirin (acetylsalicylic acid). MW = 180.16g/mol. 5g aspirin X 1mol = 0.027 mol. 180.16g. 2. Calculate the theoretical yield the number of 

Aspirin synthesis from salicylic acid.

The calculated theoretical yield was 2.520 grams. Thus the percent error was 13.93 % and the percent yield was 86.07%. The esterification reaction is a term

Calculate the theoretical yield in grams. A student was in a hurry and did not have time to filter the aspirin after acidification with HCl.

4.4 Reaction Yields

Calculate the percent yield for a reaction. The relative amounts of reactants and products represented in a balanced chemical equation are often referred to as.

Preparation of Aspirin

Therefore to calculate the theoretical yield of aspirin you will need the mass of salicylic acid used in the reaction With the initial mass of salicylic acid and the balanced equation on p 1 you can calculate how much aspirin theoretically can be made in this reaction by using the following plan:

How do you calculate a theoretical yield of aspirin?

As usual, goggles must be worn at all times. Weigh 4.0 g (0.030 mol) of salicylic acid in a 125 mL Erlenmeyer flask. Using this quantity of salicylic acid to calculate the theoretical yield of aspirin. Record the weigh on the report sheet. Carefully add 6 mL (0.051 mol) of acetic anhydride to the flask.

How do you weigh crude aspirin?

Wash the crystals with two 10-mL portions of cold water followed by one 10 mL portion of cold ethanol. Allow the crude product to dry, then weigh it on the rough balance. 2 Weigh a watch glass. Add the crystals and re-weigh. Calculate the weight of crude aspirin. Determine the percent yield.

What is theoretical yield?

The theoretical yield is the maximum amount of product that you can recover from your experimental conditions. In order to obtain the theoretical yield, convert the amount of moles of product (from the limiting reagent) to grams, using the product’s formula weight.

How do you calculate the theoretical yield of a limiting reagent?

In order to obtain the theoretical yield, convert the amount of moles of product (from the limiting reagent) to grams, using the product’s formula weight. In the laboratory, however, you will find that you will invariably lose small quantities of your material along the way.
