Question

The Hydrocarbon contains 79.87% of carbon and 20.13% of hydrogen. what is its empirical Formula. ​

Answer 1

Answer:

The empirical formula is CH3

consider the composition of carbon and hydrogen is=79.87% and 20.13%.

The molar masses of carbon and hydrogen is 12 and 1.

The moles will be 79.87/12=6.65(Carbon)

The moles will be 20.13/1=20.13(hydrogen)

Finally the atomic ratio for carbon will be 6.65/6.65=1

For hydrogen will be 20.13/6.55=3.02

The simplest ratio will be 1 and 3

so empirical formula will be CH3

Answer 2

Answer:

CH3

Explanation:

The composition of carbon and hydrogen is=79.87% and 20.13%.

The molar masses of carbon and hydrogen is 12 and 1.

Then the no. of moles of carbonwill be 79.87/12=6.65

The no. of moles hydrogen will be 20.13/1=20.13

Final the atomic ratio for carbon is

6.65/6.65=1

And for hydrogen will be 20.13/6.55=3.02

The simplest ratio will be 1 and 3

so empirical formula will be CH3
