the idea of this problem is very easy as the following ..........................................

to determine the empirical formula of this compound you should calculate
the mass of carbon in carbon dioxide produced= (12*0.1919)/44

the mass of hydrogen in water produced =(2*1*0.1172)/18
the mass of oxygen =0.1-(the sum of mass of C+the mass of H)

after determination the masses of
( C / H/O) you can use the known steps for determination the empirical formula ........more details call me at 0121996109
