The number of atoms of Chromium and oxygen are `4.8xx10^(10) and 9.6xx10^(10)` respectively. Its empirical formula is

A

`Cr_(2)O_(3)`

B

`CrO_(2)`

C

`Cr_(2)O_(4)`

D

`Cr_(2)O_(7)`

Text Solution

Verified by Experts

The correct Answer is:
B

`{:(ul("Element"),ul("R.N.A"),ul("S.R")),("Chormium",4.8xx10^(10),(4.8xx10^(10))/(4.8xx10^(10))=1),("Oxygen",9.6xx10^(10),(9.6xx10^(10))/(4.8xx10^(10))=2):}`
`therefore E.F=CrO_(2)`
