    The empirical formula is NO₂.

    Assume that you have 100 g of the compound.

    Then you have 63.65g N and 36.35 g O.

    Now, we must convert these masses to moles and find their ratios.

    From here on, I like to summarize the calculations in a table.

    Element Mass/g Moles Ratio Integers

    N 63.65 4.543 1 1

    O 36.35 2.2719 2.000 2

    The empirical formula is NO₂.
