Answer:

#"....A chemical formula......."#

Explanation:

A chemical formula is a shorthand that represents the proportion or number of chemical elements in a compound or molecule. For the molecule #"butane"#, we could represent this as #C_4H_10#, or we could give a bit more information on the formula:

#H_3C-CH_2-CH_2-CH_3#, which shows the connectivity of the molecule.
