Question

What is the empirical formula of P4O6?

Answer 1

The empirical formulas refer to the formulas where the ratios are the simplest, while the molecular formula shows the number of each type of atom.

In this case, we have a molecular formula and we just have to simplify the number to get the empirical formula. Divide each number by 2.

`\begin{gathered} (4)/(2)=2 \\ (6)/(2)=3 \end{gathered}`

Therefore, the empirical formula is

`P_2O_3`
