Benzene has empirical formula of CH
Ethylene Glycol is an organic compound.
It has a molecular formula of C6H6
Which means it has 6 carbon atoms, and 6 hydrogen atoms.
To find the empirical formula for any compound we need to know how many atoms of different types are present like in case of benzene there were 6 carbon ,and 6 hydrogen atoms
empirical formula means we need to get the simplest ratio of all these atoms, so here we would divide the each different number of atoms by 6 as all these have 6 as a common factor
6 / 6 = 1 ( for Carbon )
6 / 6 = 1 ( for Hydrogen )
Hence the empirical formula becomes : C1H1 / CH
