Vsevolod [243]

The empirical formula will be CHCl

<h3>What is the empirical formula?</h3>

The simplest whole number ratio of atoms in a compound is the empirical formula of a chemical compound in chemistry.   Sulfur monoxide's empirical formula, SO, and disulfur dioxide's empirical formula, S2O2, are two straightforward examples of this idea. As a result, both the sulfur and oxygen compounds sulfur monoxide and disulfur dioxide have the same empirical formula. They do not, however, have the same molecular formula, which specifies how many atoms are present in each molecule of a chemical compound.

For saran

C= 24.8% ,

H= 2.0% ,

Cl =  73.1%

n_{c}= 24.8/ 12 = 2.0

n_{H} = 2.0/1=2.0

n_{Cl} = 73.1/ 35 = 2.0

Now, dividing each mole by the smallest moles (hydrogen's moles), one obtains:

C= 2.0 / 2.0 = 1

H= 2.0/2.0 = 1

Cl = 2.0/ 2.0 = 1

The empirical formula will be CHCl
