Homework Help: Molar Ratios- Help Please! 8)

  1. Nov 27, 2007 #1
    I'm new to this site so I'm not sure how this really works or if anyone will really answer at all.

    I have a huge test coming up and I need to learn how to find mole ratios. If someone could help me out I would really appreciate it.

    Here are a couple of example problems maybe you could start with.

    H2O + KO2 KOH + O2


    H2O to O2

    Thanks 8)

    I'm afraid that mole ratios is a bit vague. Your examples seem straightforward enough to determine by simple inspection, so I'm sure that I don't quite get what you are confused about.

    With this:
    you probably meant this:

    H2O + K2O --------> 2KOH

    so the mole ratio of H2O to O2 doesn't make sense to me. That said, if you meant to ask what you typed in the post, the answer is simple... the ratio of water to oxygen is 1:1 (by inspection).
