Question

an organic compound contains 39.5 % of carbon 6.4 % of hydrogen and 50 4.1 % of oxygen calculate the empirical formula of the compound​

Answer 1

.

Explanation:

..........................

Answer 2

Answer:

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
