The theoretical yield of aspirin is <u>1.23 g</u>
Aspirin is a common drug with many uses. It relieves pain and reduces the risk of serious problems such as heart attack and stroke. It comes in many forms, including:
It is important to remember that aspirin alone does not lower blood pressure. However, its ability to thin the blood may benefit some people with high blood pressure.
moles of salicylic acid = mass / molar mass
=> 0.9457 / 138.2 = <u>0.006843 mol</u>
Acetic anhydride is in excess. Thus salicylic acid is the limiting reactant.
Total moles of aspirin that can form = moles of salicylic acid = 0.006843
mass of aspirin = number of moles of aspirin x molar mass of aspirin
= 0.006843 mol x 180.16g/mol = 1.23g
Thus theoretical yield of aspirin = 1.23 g

Two moles because one moles would be 6.02×10 23 atoms 2 moles would equal twice that number of atoms
Answer:
I'm fairly sure it's D
Explanation:
If they're more spread out than they're roots in theory should have more space. Sorry if I'm wrong
If you change the subscripts it would change the reactants or products and then you would be solving a different formula, you would change what the chemical is
