Question

If mass ratio of carbon and hydrogen in hydrocarbon is 12:1 then the empirical formula of hydrocarbon is?​

Answer 1

Answer:

CH

Explanation:

By dividing with their mass, by comparing you can get CH as the simplest version of 12:1 ratio.

hope this will help you

Answer 2

Answer:

For the given question, the empirical formula of the compound is CH .

Explanation:

• A compound's empirical formula is one that provides the straightforward whole number ratio of the atoms of the various elements present in a single molecule of the compound.

According to our question,

Mass ratio of C: H = 12 : 1

And as we already know,

molar mass ratio of C : H = 12: 1

Now, according to the formula, ratio of mass ratio and molar mass ratio is :

Mass ratio (C and H)/Molar mass ratio (C and H) = 12:1/12:1

= 1:1

Therefore, for every C atom, there are one H atoms, hence empirical formula is CH.
