On analysis, a certain compound was found to contain iodine and oxygen in the ratio of 254:80. The formula of the compound is: (At. mass I=127,O=16)

A

`IO`

B

`I_(2)O`

C

`I_(5)O_(2)`

D

`I_(2)O_(5)`

Text Solution

Verified by Experts

The correct Answer is:
D
`{:(,"Element","Wt","At.Wt, R,N.A"," S.R"),(I,254,127,(254)/(127)=2,(2)/(2)=1xx2=2),(O,80,16,(80)/(16)=5,(5)/(2)=2.5xx2=5):}`
`thereforeE.F=CrO_(2)`
