titration of NaOh & ethanoic acid?

Question

did a titration with NaOh and ethanooic acid to find the concentration of ethanoic acid, now that ive found the concentration of the undiluted acid, how do i find the % mass of the acid?

Answer 1

Graph your titration values on excel, from the equivalence point, molarity of NaOH, and mass of acid, you should be able to calculate the GMW. First use M1 V1= M2 V2. Then #gacid/ GMWacid = Mbase X Vbase. Hope that helps.

Answer 2

If, say, your ethanoic acid came out to be 1M, then that would be 60g per 1000g of solution, which is 6%.

So it's molarity x Mr x 100/1000.
