A student investigated the extent of hydrolysis in a old sample of the fat used in part 10a. The carboxylic acid extracted from a 2.78g sample of this fat (Mr 806.0) reacted with 24.5cm3 of a 0.150 mol dm-3 solution of NaOH. Calculate the percentage of the fat that had hydrolysed

What have you tried, so far?
I have the number of moles of NaOH (3.68 x 10^-3) and miles of fat (3.45 x 10^-3), don’t know what to do now

Is it a triglyceride fat?

If it is, 1 mol of fat produces 3 mol of fatty acid (on hydrolysis), which in turn would react with 3 mol of NaOH.
