Answer: Hydrogen atoms indicate a hydrate of hydrogen

Explanation: (CH2O)n is the impirical formula of carbonhydrate, which can be stated as: Cn + H2n + On, that is, 12n + 2n +16n = 30n (where n is number of moles)

CO2 is the molecular formular for carbon (IV) oxde and molar mass is given as: C + O2 = 12 + (16 X 2) = 12 + 32 = 44g
