An organic compound contains carbon 80% and hydrogen 20%. If molecular

1.	An organic compound contains carbon 80% and hydrogen 20%. If molecular mass is 30. calculate molecular formula.
Answer» C= 80/12 = 6.6/6.6= 1 H = 20/1= 20/6.6= 3 empirical FORMULA= CH3 n= 30/15 n= 2 molecular formula= C2H6

An organic compound contains carbon 80% and hydrogen 20%. If molecular mass is 30. calculate molecular formula.

Answer»

C= 80/12 = 6.6/6.6= 1

H = 20/1= 20/6.6= 3

empirical FORMULA= CH3

n= 30/15

n= 2

molecular formula= C2H6
