How did you know to work out the moles by using the 250cm3 and not using the 100cm3? and i also thought the moles that reacted with aspirin is the 4.47x10-3. i'm very confused on how you get moles of aspirin as 0.0053
When we work out mean titre I thought concordant results to 0.1 dp so if the question did ask state the mean titre would we give it as 22.4 or 22.35. In this case I wasn’t too sure if when working out moles of HCl I would do 0.2 x 0.2235 or 0.2 x 0.224. Thank you for your help I really appreciate it James

How did you know to work out the moles from the 250cm3 and not take into account the 100cm3 for moles?
