please help
Mustrates treat all types of ilnesses. Background Aspirin is a prodrug of salicylic acid, the actual active drug. A compound related to salicylic acid, salicin, was first isolated from willow bark in the mid 1700's, but willow-bark extract was used by the andient Greeks as a treatment for pain and fever. Salicylic acid (and many related phenols) are very hard on your Ho stomach, but when esterified, as aspirin is, they are much better tolerated. Simple esters are...

2) If you were to use 3.17 g of starting material, how much
product would you expect? Again, show your work.
3) Why is phosphoric acid added to the reaction?
4) A small amount of water is added at the end of the reaction
to react with the excess acetic anhydride. Show a balanced equation
for that reaction.

Question 4 (2 points) if you accidently read the procedure wrong while doing the synthesis of aspirin and mixed Sg of salicylic acid with 2 mL of acetic anhydride (instead of correctly mixing 2g of salicylic acid with 5 mL of acetic anhydride), what would be the effect7(density of acetic anhydride = 1.082 g/mL) a Nothing, it would still work just fine Ob Reaction would work fine, but less product would form since acetic anhydride is...

Please help me solve this and show the full calculations. Calculate the limiting reactant, theoretical yield, and percent yield using the following: 2.0 g of salicylic acid and 5 mL of acetic anhydride, along with 10 drops of phosphoric acid, were used to make acetylsalicylic acid. This is a 1:1 mole ratio.
