    The empirical formula is XeO₃.

    Explanation:

    Assume 100 g of the compound is present. This changes the percents to grams:

    Given mass in g:

    Xenon = 73.23 g

    Oxygen = 26.77 g

    We have to convert it to moles.

    Xe = 73.23 / 131.293 = 0.56 moles

    O = 26.77 / 16 = 1.67 moles

    Divide by the lowest value, seeking the smallest whole-number ratio:

    Xe = 0.56 / 0.56 = 1

    O = 1.67 / 0.56 = 2.9 ≈3

    So the empirical formula is XeO₃.
