I have a quick question about atomic weight. The atomic weight for Na is 22.98977 now would I round this to 23 or 22.9 or 22.98. Sorry if it's a little silly.

OpenStudy (amurciano2):

22.99

OpenStudy (grimsnightmare):

Thank you

OpenStudy (grimsnightmare):

Sorry. So for 126.9045 I would only make it 126.90?

OpenStudy (amurciano2):

Yes. It is usually two decimal places and normal rounding rules for the hundredth place

OpenStudy (grimsnightmare):

Thank you very much!
