Which must be the same when comparing 1 mol of oxygen gas, o2, with 1 mol of carbon monoxide gas, co? a)the mass b)the volume c)the number of molecules d)the number of oxygen atoms

Answer : The correct option is, (C)the number of molecules

Explanation :

When we are comparing 1 mole of oxygen gas with 1 mole of carbon monoxide gas then we conclude that,

In 1 mole of oxygen gas , there are two number of molecules of oxygen.

In 1 mole of carbon monoxide gas , 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.
