Question

A hydrocarbon has 3 gram of carbon per gram of hydrogen hence it's simplest formula will be ??

Answer 1

Answer:- Simplest formula is $CH_4$ .

Solution:- The hydrocarbon has 3 grams of C per gram of H.

An empirical formula shows the simplest ratio of moles of atoms present in the compound. So, let's convert the grams to moles and calculate the simplest ratio of moles of atoms of C and H.

$3gC(\frac{1mol}{12g})$  = 0.25 mol C

$1gH(\frac{1mol}{1g})$  =  1 mol H

For the ratio, we divide the moles of each by the least one of them. Moles of C are less than moles of H, so we will divide the moles of each by the moles of C to get the ratio:

C = $\frac{0.25}{0.25}$  = 1

H = $\frac{1}{0.25}$ = 4

Ratio of moles of atoms of C to H is 1:4. hence, the simplest formula is $CH_4$  .
