Answer : The volume of 1 mole of
and
gases are the same.
Solution: Given,
Moles of
= 1 mole
Moles of
= 1 mole
Moles of
= 2 mole
Formula used for ideal gas is :
P V = n R T
According to the question, the gases are at standard temperature and pressure. So, the volume of gases only depends on the number of moles. This means that the higher the number of moles, higher will be the volume of gas.
The moles of
are more than the moles of
and
. So, the volume of
will be more.
And the moles of
and
are equal. Therefore, their volumes are also equal.
Therefore, the best option is the volume of 1 mole of
and
gases are the same.
