Question

the hydrogen contain 79.89% carbon and 20.13% of hydrogen.what is it's empirical formula ? we​

Answer 1

Answer:

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
