(a) Butyric acid contains only \( C, H \) and \( O . A 4.24 \mathrm{mg} \) sample of butyric acid is completely burned. It gives \( 8.45 \mathrm{mg} \) of \( \mathrm{CO}_{2} \) and \( 3.46 \mathrm{mg} \) of water. What is the mass percentage of each element in butyric acid?
(b) If the elemental composition in butyric acid is \( 54.2 \% C ; 9.2 \% \mathrm{H} \) and \( 36.6 \% \mathrm{O} \), determine the empirical formula.
(c) Molecular mass of butyric acid is 88 . What will be its molecular formula?
