Thanks haris, now i understand the calculations part, however I dont quite understand why mg is the limiting reagent and how can we know if it has been used up? Other than this, you didnt answer how many moles of the other reagent (in this case ethanoic acid) are left unreacted.
By the way, do u knw any good websites on moles?
