Text Solution

Verified by Experts

The correct Answer is:
D
One molecule of CO contains one oxygen atom.
`therefore 6.02 xx 10^(24)` molecules of CO contain `6.02 xx 10^(24)` oxygen atoms.
`6.02 xx 10^(23)` atoms of oxygen = 1 g-atom of oxygen
`therefore 6.02 xx 10^(24)` atoms of oxygen = 10 g-atom of oxygen.
