Answer : The correct option is, (C)the number of molecules
Explanation :
When we are comparing 1 mole of oxygen gas [tex](O_2)[/tex] with 1 mole of carbon monoxide gas [tex](CO)[/tex] then we conclude that,
In 1 mole of oxygen gas [tex](O_2)[/tex], there are two number of molecules of oxygen.
In 1 mole of carbon monoxide gas [tex](CO)[/tex], there are two number of molecules (carbon and oxygen).
Hence, the number of molecules must be the same when comparing 1 mole of oxygen gas, with 1 mole of carbon monoxide gas.
