Hi there,

I hope these help you :)

Work through these yourself too, especially the yield calculation as this will come up a lot in your lab studies!

Good luck!

1. There are currently 15.2 mmol Salicylic acid (2.1/138) and 36.3 mmol acetic anhydride ([4/1.08]/102.1)
So there are 2.4 equvalents of acetic anhydride to salicylic acid
- the theoretical yield would be unaffected since salicylic acid is still the limiting reagent!
- if you ...
