Question

calculate the emperical formula of a compound "A" which is obtained
from the catalytic hydrogenation of acetiline if this compound
contains 92 7% carbon and 7 3% hydrogen???

Geetha · Accepted Answer

The given equation is catalytic hydrogenation of acetylene So
either the product is ethylene or ethane

Element
%
At mass
% / at mass
Simple ratio
Whole number ratio

C
92 7
12
92 7/12 = 7 725
7 725 / 7 3 =1 06
1

H
7 3
1
7 3/1 = 7 3
7 3 / 7 3 =1
1

Thus the empirical formula of the compound is CH

Element	%	At mass	% / at mass	Simple ratio	Whole number ratio
C	92.7	12	92.7/12 = 7.725	7.725 / 7.3 =1.06	1
H	7.3	1	7.3/1 = 7.3	7.3 / 7.3 =1	1
