Moles of iodine =(247/127)=2 Moles of oxygen =80/16=5 Formula =I2O5

Q. On analysis a certain compound was found to contain iodine and oxygen in the ratio of $254 g$ of iodine (at. mass $127$ ) and $80 g$ oxygen (at. mass $16$ ). What is the formula of the compound ?

$I O$

$I_{2} O$

$I_{5} O_{3}$

$I_{2} O_{5}$

Moles of iodine $= \frac{247}{127} = 2$
Moles of oxygen $= 80/16 = 5$
Formula $= I_{2} O_{5}$
