Answer 2

Answer:

CH3

Explanation:

it is given in question that the hydrocarbon contains 80% carbon & 20% hydrogen.

• now,the atomic number or mole number of carbon & hydrogen are 12 & 1 respectively.

here,we can easily calculate the mole ratio of carbon & hydrogen using this fromula :

the mole ratio of Carbon & hydrogen = (% carbon present in hydrocarbon / atomic or mole number of carbon) : ( % hydrogen present in hydrocarbon / atomic or mole number of hydrogen)

=(80÷12) : (20÷1)

=20 :60= 1:3

so, the empirical formula is CH3 ( answer)
