Asked by Aaron
A student dissolves a .726 g aspirin tablet in water and titrates the solution with .272 M NaOH are required to reach the equivalence point. Calculate the percentage of acetylsaliclic acid in the tablet.
I am not really sure where to start with this. I unfamiliar with problems like these.

I use this most often but it's a couple of equations put together.
mL x M x (molar mass/1000) = grams
You don't list mL in the problem and you must have that. M - 0.272. Molar mass acetylsalicyclic acid you can look up. Calculate grams.
Then % ASA = (grams ASA/0.726 sample)*100 = ?
