Lab question asks what the precision of the scale. The scale reports out like this: 56.231g.

So I would say this scale is precise to 0.001 g correct? I ask because I've read about some uncertainty being reported as ±.0005 g .

Furthermore, if a buret's graduations are .1 mL increments, I would report my measurements to an extra decimal place out. Ex: 2.45mL

However, am I correct in assuming that the buret's precision is within 0.1 mL? Thanks for the help. My textbook isn't exactly helping.

The burette should say on the side what the error is. If the increments are 0.1ml apart it would be difficult to report to 3dp. I know at school teachers will tell you to report to 2dp even though this method relies entirely on human judgement of where the meniscus is.

Depends on the glassware class, see discussion here:
