Question

An organic compound contains c = 36% , h=6% what is the emperical formula

Answer 1

Answer:

CH2

Explanation:

Percentage of carbon==>36

Percentage of hydrogen ==>6

Atomic mass of carbon ===>12 gram per mole.

Atomic mass of hydrogen ==>1 gram per mole.

Now divide the mass percentage by atomic mass of the element.

Carbon ==>36/12=3

Hydrogen ==>6/1=6

To calculate empirical formula we should calculate the simplest ratio .

For this divide the equation 1 by the smallest result .

Carbon=>3/3=1

Hydrogen ==>6/3=2

The empirical formula is CH2.
