2C + O2 = 2CO.
2mol of CO = 1 mol of O2,
2 * 6.02 * 10^23 molecules of CO= 1g molecule of O2( bcs 1 mol = 6.02 * 10^23 molecules)
6.02 * 10^24 molecules of CO= ?
= 6.02 * 10^24/ 2,
= 6.02 *10^23.
= 10/2= 5 g molecules of O2.
2mol of CO = 1 mol of O2,
2 * 6.02 * 10^23 molecules of CO= 1g molecule of O2( bcs 1 mol = 6.02 * 10^23 molecules)
6.02 * 10^24 molecules of CO= ?
= 6.02 * 10^24/ 2,
= 6.02 *10^23.
= 10/2= 5 g molecules of O2.

When we have one gram then why we need mole?

C is the correct answer.
CO has 16g O. i.e. half the amount of O2 (32g).
Now. Moles will be 6.022 * 10^24 * 1/2 ÷ 6.022 * 10^23.
i.e. equal to 5 moles (gm molecule).

Yes, 100% c is correct.
@Ghost Rider, you had given a very nice explanation.

Actually, my dear friends thank you very much for giving such wonderful answers.
But I have a doubt on a mole, 1mole = 6.023*10^23 molecules, then 2moles means double the 1 mole i.e.12.046 * 10^46 molecules, then for 10 moles = 60.23 * 10^230.
I am getting this one, how did you get 6.023 * 10^24?
