Question

How do you solve chemical formula?

Answer 1

Do you refer to `"empirical formula.......?"`

Explanation:

See here, and here for a specific example........

And note that to solve for the empirical formula, the simplest whole number ratio defining constituent atoms in a species, we need first to MEASURE `%C`, `%H`, `%N` by some means. Usually this involves combusting a known mass of compound and shunting the product carbon dioxide and water gases down a gas chromatograph where their proportions are analysed according to a standard.
