Question

Compound X has the following composition by weight:

Carbon (C) 64.8%, Hydrogen (H) 13.6%, and Oxygen (O) 21.6%.

Determine the empirical formula for compound X.

Answer 1

Answer:

C2H4O

Explanation:

Let amount of organic = 100 gm

amount of carbon = 54.55 g

amount of hydrogen = 9.09 g

Amount of oxygen = 36.26 g

number of mole of carbon =

12

34.55

=4.54583

number of mole of hydrogen =

1.018

9.09

=9

number of mole of oxygen =

16

36.26

=2.26

4.54833:9:2.26
