Some Basic Concepts Of Chemistry Question 35
Question: A compound contains 54.55 % carbon, 9.09% hydrogen, 36.36% oxygen. The empirical formula of this compound is:
Options:
A) $ C _3H _5O $
B) $ C _4H _8O _2 $
C) $ C _2H _4O _2 $
D) $ C _2H _4O $
Show Answer
Answer:
Correct Answer: D
Solution:
[d] C (54.55) =54.55/12=4.5 4.5/2.27=2
H (9.09) 9.09/1-9.09 9.09/2.27=4
O (36.36)_ 36.36/16=2.27 2.27/2.27= 1
Hence empirical formula of the compound $ =C _2H _4O $
