Question

What is the percentage composition for hydrogen in the compound c2h4

Answer 1

14.37%

Step-by-step explanation:

B

Answer 2

ANS: C = 85.63 %; H = 14.37 %

C = 2 x 12.01 u = 24.02 u

H = 4 x 1.008 u = 4.032 u

TOTAL = 28.052 u

% C = (24.02/28.052) x 100 % = 85.63 %

% H = (4.032/28.052) x 100 % = 14.37 %
