Answer:
The volume of the helium gas is 45 cm³.
Explanation:
The volume of the helium gas can be determined from kinetic theory of gases, which states that gas molecules do not have a fixed volume, rather they assume the volume of their container.
Therefore, if the volume of the balloon is 45 cm³, which is also the container of the helium gas, then the volume of the helium gas is 45 cm³.
