How many moles of acetylsalicylic acid (aspirin) would it be possible 2 prepare based on the amnt of salicylic

There should be more acetic anhydride left than salicylic acid. Since acetic acid anhydride is present in excess, how many moles of acetylsalicylic acid (aspirin) would it be possible to prepare based on the amount of salicylic acid you started with ??





C7H6O3 + C4H6O3 =%26gt; C9H8O4 + C2H4O2


(salicylic acid)(acetic anhydride)(acetylsalicylic acid)(acetic acid)





molar mass of acetic anhydride = 102.1 g/mol


moles of acetic anhydride = 0.11





molar mass of aspirin = 180.12 g/mol


moles of aspirin = 0.011 mol


mass of aspirin = 1.9 g





mass of salicylic acid = 1.9 g


moles of salicylic acid = 0.014 mol





any ideas???

How many moles of acetylsalicylic acid (aspirin) would it be possible 2 prepare based on the amnt of salicylic
In your balanced equation, one mole of salicylic acid forms one mole of aspirin, so 0.014 mol of salicylic acid forms how much aspirin?
