# What does the chemical formula of a compound tell you about the compound?

For example, the chemical formula for glucose is ${\text{C"_6"H"_12"O}}_{6}$.
We can also think of a compound in terms of moles, where 1 mole of $\text{C"_6"H"_12"O"_6}$, contains 6 moles C atoms, 12 moles H atoms, and 6 moles O atoms.
