A certain organic compound is known to contain only carbon, hydrogen and oxygen.
The compound was analysed as follows.
A 2.149g sample was burned and the carbon dioxide produced was bubbled through a barium hydroxide solution, producing 11.27 g of barium carbonate ($BaCO_{3}$)
$$CO_{2} + Ba(OH)_{2} \to BaCO_{3} + H_{2}O $$The mass of water produced by burning of the sample was 0.7721g.
The compound was found to have a molecular weight of 150.1 gmol$^{-1}$.
