Microanalysis of an organic compound containing carbon, hydrogen, and oxygen, gives #62.6%*C#, and #4.21%*H#. What is the empirical formula of the compound?
We assume a
In each case, we have divided the mass of element by the ATOMIC mass of each element to give an elemental ratio.... How did I know that the compound was
And now we divide thru by the LOWEST molar quantity, that of oxygen to get a trial empirical formula of
We cannot access the molecular formula inasmuch as we need a measurement of molecular mass. See here.
