Question

The hydrocarbon contains 79.8 7% Karbonn and 20. 13% of hydrogen what is its empirical formula

Answer 1

The hydrocarbon contains 79.8 7% Karbonn and 20. 13% of hydrogen what is its empirical formula

solution : hydrocarbon contains 79.87% of carbon and 20.13% of hydrogen.

finding percentage mass composition of each of the elements.

for carbon (C) ⇒79.87/12 ≈ 6.655

for hydrogen (H)⇒20.13/1 = 20.13

now finding simple ratio of these compositions.

C : H = 6.655 : 20.13

= 6.655/6.655 : 20.13/6.655

= 1 : 3

hence, empirical formula of hydrocarbon is $CH_3$
