Let’s say I have a class A 25ml pipet with an uncertainty of +/- 0.24ml.
If I want to express the volume of the pipet to the correct number of sig figs to say determine the sig figs in a final answer - what is it?
Is it 25 ie two, because that is the marking?
Or 25.00 ie four, because the uncertainty limits the range to 24.76 – 25.24, which are 4 sig fig values?
Or 25.0 ie three, being 0.24 rounded down to the nearest single sig fig?
Thanks!
