If 0.150 moles of salicylic acid and execs acetic anhydride are used during a synthesis of aspirin, how many grams of aspirin will be obtained if the reaction gives a 38% yield?

The rxn is 1:1 meaning that 1 mol aspirin is produced from 1 mol salicylic acid.

Therefore, 0.150 mol S.A will produce 0.150 mol aspirin. That is the theoretical yield. That x 0.38 will give you the actual yield in mols and mols x molar mass aspirin = grams aspirin actually collected.

To calculate the grams of aspirin obtained, we'll need to use the following steps:

Step 1: Write the balanced equation for the synthesis of aspirin.
The balanced equation for the synthesis of aspirin is:

C7H6O3 + C4H6O3 → C9H8O4 + CH3COOH

Step 2: Determine the molar ratio between salicylic acid and aspirin.
By examining the balanced equation, we can see that the molar ratio between salicylic acid (C7H6O3) and aspirin (C9H8O4) is 1:1. This means that for every 1 mole of salicylic acid used, 1 mole of aspirin is obtained.

Step 3: Calculate the moles of aspirin obtained.
Since the molar ratio is 1:1, the number of moles of aspirin obtained will be the same as the number of moles of salicylic acid used, which is 0.150 moles.

Step 4: Calculate the grams of aspirin obtained.
To calculate the mass of aspirin obtained, we need to multiply the number of moles of aspirin by its molar mass. The molar mass of aspirin (C9H8O4) is:

(12.01 g/mol × 9) + (1.01 g/mol × 8) + (16.00 g/mol × 4) = 180.16 g/mol.

0.150 moles × 180.16 g/mol = 27.02 grams.

Step 5: Calculate the yield of aspirin.
The given yield is 38%. To find the actual mass of aspirin obtained, we multiply the calculated mass by the yield:

27.02 grams × 0.38 = 10.27 grams.

Therefore, approximately 10.27 grams of aspirin will be obtained if 0.150 moles of salicylic acid and excess acetic anhydride are used during the synthesis, assuming a 38% yield.

Well,

If 0.150 moles of salicylic acid and execs acetic anhydride are used during a synthesis of aspirin, how many grams of aspirin will be obtained if the reaction gives a 38% yield?
So, let us refer to the common history of knowledge to help us answer this question. First off, the widespread production of the refrigerator began in 1942. This helped us contain and secure stable salicylic acid acetic acid. This helped us produce a grand total (and the answer to your question) of 2 grams of aspirin which we multiply by 100 since its in perCENT yield. this leaves us with 2.00 grams of aspirin that will be produced in this reaction.
