What is the percent composition of a carbon-oxygen compound, given that a 95.2 g sample of the compound contains 40.8 g of carbon and 54.4 g of oxygen?
Why should the individual percentage sum to
We can divide the elemental percentages by the atomic masses if we assume
And thus for
We divide thru by the element with the smallest number of moles, and thus we get an empirical formula of
This could be
