Question

WHAT IS THE EMPIRICAL FORMULA OF C9H20

Answer 1

Actually, C9H2O is already the empirical formula

Empirical Formula is the lowest possible of number ratio for the compound (without making it into decimals)

Example :

C2H6 , the empirical formula would be : CH3

hope this helps

Answer 2

Answer : The empirical formula of $C_9H_{20}$ is $C_9H_{20}$.

Explanation :

Empirical formula : It is the simplest form of the chemical formula which depicts the whole number of atoms of each element present in the compound.  

Molecular formula : it is the chemical formula which depicts the actual number of atoms of each element present in the compound.

As we are given the formula of compound $C_9H_{20}$.

According to the empirical formula, the atoms of each element present in the compound should be in simplest whole number.

The given compound is already in simplest whole number. So, the empirical formula will be same as $C_9H_{20}$.
