Answer:

The chemical formula of the compound is P_2O_5.

Explanation:

In 1 mole of P_2O_x there are 2 moles of phosphorus atom.

Then 3.3 moles of phosphorus will be in :

\frac{1}{2}\times 3.3 mol=1.65 moles

In 1 mole of P_2O_x there are x moles of oxygen atom.Then 1.65 moles of compound will have :

1.65 mol\times x

Moles of oxygen in 1.65 moles of compound = 8.20 mol

1.65 mol\times x=8.20 mol

x=\frac{8.20 mol}{1.65 mol}=4.9 \approx 5

The chemical formula of the compound is P_2O_5.
