If the "actual" formula is what's required I don't see why empirical formulas are needed. Any help would be appreciated.

What is actual? Theoretical and empirical I know. When theoretical formulas are not known exactly, empirical formulas are used. Empirical formulas work in some conditions.
Empirical means practically observed.

You can use it to find or determine the molecular formula for a compound only if the molar mass of the compound is known
The term empirical refers to the process of elemental analysis, a technique of analytical chemistry used to determine the relative percent composition of a pure chemical substance by element.
In physics, an empirical formula is a mathematical equation that predicts observed results, but has no known theoretical basis to explain why it works.
hope that helps
