The number of gram atoms of oxygen in `0.2xx10^(24)CO` molecules is

A

`1`

B

`0.5`

C

`5`

D

`9`

Text Solution

Verified by Experts

The correct Answer is:
D
`6.02xx10^(23)` molecules of CO = 1 mole of CO
`6.02xx10^(24)` moles of CO = 10 moles of CO
1 mole of CO contain 1 g atom of oxygen
10 moles of CO contain 10 g atoms of oxygen
