hi guys I've had this nagging problem in chem for a while
say in the empa it asks you to work out a given value
say it comes to 109.89088987
`i round that to 3sf to get 110
Then in part(ii) it asks me hence to work out say percentage error for 100 the true value
Do i sub in my rounded answer of 110 or my accurate answer of 109.89088987 to get my answer for this part (ii) answer
thanks this has been annoying me for ages becos using my rounded answer could introduce rounding errors
