A gaseous compound containing carbon and hydrogen was analyzed and found to consist of 83.65% carbon by mass. What is the empirical formula of the compound

Explanation:

The empirical formula of a compound represents the ratio of elements present in it but not the actual number of atoms.

Let the total mass of compound is 100 gram.

Then  mass of carbon would be is 83.65 gram .

Moles of carbon = 83.65/12 = approx 7 mole  (approx)

Mass of hydrogen present in the compound would be 100 - 83.65

                                                                                        = 16.35  gram

Moles of hydrogen = 16.35/1 = 16 mole (approx)

Therefore, the empirical formula of the compound would be
