Answer:

Formula of the compound = [tex]P_2O_5[/tex]

Explanation:

Given,

No. of mole of O = 8.20 mol

No. of mole of P = 3.30 mol

Chemical formula = [tex]P_2O_x[/tex]

Ratio of P and O = [tex]\frac{2}{x}[/tex]

[tex]\frac{2}{x} =\frac{3.3}{8.20} \\x \times 3.3 = 8.20 \times 2\\x = \frac{8.20 \times 2}{3.3} \\x=4.9969\\ = 5[/tex]

formula of the compound = [tex]P_2O_5[/tex]
