1gm of oxy contains 6.023x10^23 no. of moles. therefore 6.023x10^24 no. of moles will be in 10gm of oxy molecule. the ans should be option D.

Its 5g molecule because 1g of CO molecule has 6.022*10^23 molecule of CO. Therefore 6.022*10^24 molecules has 10g of CO molecule. Hence out of 10g 5g is for only C.

What @Swapnil sontakke said is right. only 1 gm of O2 has 6.022*10^23 molecules.
Therefore 6.023x10^24 no.of moles will be in 10 gm of O2 molecule.
Since in CO only 1 atom of Oxygen is present the answer is C.
Therefore 6.023x10^24 no.of moles will be in 10 gm of O2 molecule.
Since in CO only 1 atom of Oxygen is present the answer is C.

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.

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

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.

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