I am agreed with @Swapnil Sontakke discussion since 6.023 * 10^24 is given, so the answer must be 10.

Answer is C.
Remember CO.
C and O.
Has one mole each then.
10/2 = 5.
C is correct.

5 gram is correct because number of gram-molecules means number of moles of O2 molecules. Now 6.02 x 10^24 CO molecules = 10 moles of CO (divided by 6.02 x 10^23) 1 mole of CO has 16 g or 0.5 mole of O2.
Therefore 10 moles of CO will give 10 x 0.5 = 5 moles or gram-molecules of O2 (oxygen).
Therefore 10 moles of CO will give 10 x 0.5 = 5 moles or gram-molecules of O2 (oxygen).

1 CO molecule contains 1 O-atom.
1 mole CO equivalent to 6.02x10^23 molecules of CO contain 6.02x10^23 atoms of Oxygen. So 6.02x10^24 CO molecules contain 6.02x10^24 atoms of O which is equivalent to 10 gm-atoms of oxygen.
Since Oxygen is diatomic, 10 g-atom = 1/2x10 g-molecule of Oxygen = 5 gram-molecule of O2 = 5 grams of O2 molecule.
Note: 6.02x10^23 atoms = 1 gm-atom.

Answer will D b/c 6.023*10^24/6.023*10^23=10.

I think 6.023*10^23+10^1 we can consider 6.023*10^23 = 1.
So 10^1 = 10.
CO = 12+16 = 28.
O = 16.
28/16 = 1.75.
10/1.75 = ~2.
Therefore 10/2 = 5.
So 10^1 = 10.
CO = 12+16 = 28.
O = 16.
28/16 = 1.75.
10/1.75 = ~2.
Therefore 10/2 = 5.

Answer C is correct because C+0.5 O2 = CO.
No. of g mole of CO = (6.02x10^24)/(6.02x10^23) = 10 g mole.
Therefore g-mole of O2 = 10x0.5 = 5.
No. of g mole of CO = (6.02x10^24)/(6.02x10^23) = 10 g mole.
Therefore g-mole of O2 = 10x0.5 = 5.

Is at correct g-molecule means gas molecule? then the answer is C. Otherwise the answer should be D.
Clint said:

It should be letter D.
Whatever the formula of a certain substance, a mole of it will always contain 6.022x10^23 molecules. Thus, 6.02x10^24 molecules of any substance contains 10 moles of it, whether it is CO2, CO, or even DNA.
