# What is the empirical formula for glucose?

The empirical formula for glucose is $\text{CH"_2"O}$.
The molecular formula for glucose is $\text{C"_6"H"_12"O"_6}$. The subscripts represent a multiple of an empirical formula. To determine the empirical formula, divide the subscripts by the GCF of $6$, which gives $\text{CH"_2"O}$.
The empirical formula $\text{CH"_2"O}$ shows very clearly that glucose, a carbohydrate, is composed of hydrated carbon atoms.
