Aspirin is made by the reaction of salicylic acid with acetic an hydride what is the theoretical yield of aspirin if 85.0 grams of salicylic acid is treated with excess acetic an hydride?

Since salicylic acid is being reacted with excess acetic anhydride, salicylic acid is the limiting reactant of the reaction. The balanced equation of the reaction of salicylic acid and acetic anhydride indicates that their is a 1:1:1:1 ratio between every reactant and product. Based on this, it can be concluded that the moles of salicylic acid, if reacted entirely, will yield an equivalent amount of moles of aspirin. To find the theoretical yield, you must know the molecular weight of aspirin and salicylic acid. First, the amount of moles of salicylic acid must be calculated by dividing the gram amount of salicylic acid, which is 85 grams, and dividing it by its molecular weight, which is 138.12 grams per mole.
85.0/138.12= 0.615 moles of salicylic acid
This is the mole amount of salicylic acid as well as the theoretical mole amount of aspirin. To convert the mole amount of aspirin into grams, this figure be multiplied by the molecular weight of aspirin, which is 180.1598
0.615 x 180.1598 = 111 grams of aspirin (when rounded to 3 significant figures)

How do you know which OH group on salicylic acid reacts to form aspirin?
Aspirin is formed in a reaction between salicylic acid and acetic anhydride. In this reaction it is the phenolic alcohol group that reacts to form the aspirin.
What percent salicylic acid in aspirin?
37.16% is the expected yield in the reaction of salicylic acid and acetic anhydride used to form aspirin.
What is the process of making aspirin?
Aspirin is made when salicylic acid and acetic anhydride is reacted in the presence of an acid catalyst such as H2SO4. Acetylsalicylic acid (aspirin) and acetic acid is formed. The reaction is an esterification reaction.
Where was the substance in aspirin found?
Aspirin is acetyl salicylic acid.
How to write the equation for the reaction by which aspirin decomposes in an aqueous ethanol solution?
The chemical reaction is: One mole of aspirin plus one mole of water yields one mole of salicylic acid plus one mole of acetic acid. Aspirin=C9H8O4 Salicylic acid=C7H6O3 Acetic acid=C4H6O3
What is another product name for salicylic acid?
salicylic acid is most commonly known as Aspirin (it is the main ingredient in Aspirin)
What is more polar aspirin or salicylic acid?
Salicylic acid i would think Look at both their structures; salicylic acid has more polar -OH bonds
Why maintain the temperature of the reaction at 90 degrees C in synthesis of aspirin?
To prevetn evaporation of salicylic acid
What is aspirin chemically?
Acetyl salicylic acid.
Is aspirin a carboxylic acid and an ester?
Aspirin is acetylsalicylic acid and an acetate ester of salicylic acid.
What happens to aspirin if we boil it?
The active ingredient in aspirin is acetyl salicylic acid. This is an ester, and boiling it will hydrolyze the bond and break it down into acetic acid and salicylic acid.
What do willow tree bark extract oil of wintergreen and aspirin have in common?
Willow tree bark contains Salicylic acid. Aspirin is acetate of salicylic acid.
