rehwinja,
for how to determine the moles of a product, you need to first
determine which is the limiting reagent. Since it's a 1:1 ratio, you
take the amount of salicylic acid used (g), convert to moles, and use the
ratio to convert to moles of acetylcalicylic acid (using the MW). Hope
I didn't give too much away, and if I did anything wrong, someone
_please_ let me know!
