Thanks for confirming that :)
Also, I'm trying to think of certain errors that could occur during the production of aspiring.
So far I have thought of:
- slight weighing errors
- loss of substance through weighing/transferring
- inaccurate apparatus
- possiblity that not all ethanoic acid got washed out

thanks for your help :)

Aspirin is slightly soluble, so some of it could have been 'lost' during the filtration process.
