Homework Help: Significant numbers in chemistry

  1. Sep 25, 2013 #1

    I have 5.8 moles of KOH. 1Mole of KOH= 56.11g
    So: 5.8moles of KOH x 56.11g/1mole= 325.438g of KOH

    If, I want to follow the significant figures rules, what is the answer?

    Is it 330g? If yes, it seems inaccurate.

    Yes, 330g (or 3.3E2g) is correct. It probably seems a little large because you are rounding up from just over 5, but two significant figures is the correct number.
