Explanation:

mass = moles * molar mass

molar mass of carbon dioxide (CO2) = 12+32 = 44

= 19.5* 44 = 858

proof

moles = mass /molar mass

= 858/44 = 19.5 moles

I would say the answer is P2O5. Some teachers use PO2.5. I'm not one of them.

Refer periodic table
Pb= 207.2
N=14
O= 16
$207.2 \: + (14 \times 2) + (16 \times 6)$
