You find that 7.36g of a compound has decomposed to give 6.93g of oxygen. the only other element is hydrogen. if the molar mass of the compound is 34.0g/mol, what is its molecular formula?

The molecular formula of this compound is

Explanation:

From the given,

Mass of compound = 7.36 g

Molar mass of compound = 34.0 g/mol

The mass of oxygen = 6.93 g

The hydrocarbon contains only hydrogen and carbon.

Mass of hydrogen + Mass of oxygen = 7.36 g

Mass of hydrogen + 6.93 g = 7.36 g

Mass of hydrogen = 7.36 - 6.93 = 0.43g

Molar mass of hydrogen = 1.0 g/mol

Molar mass of oxygen = 16 g/mol

Now divided each one by 0.43
