Answer:
2.24 L
Step-by-step explanation:
According to Avogadro's Law, equal volumes of gases at the same temperature and pressure contain the same number of moles. Therefore, since we have 0.1 mol of O2 gas occupying a volume of 2.24 L at STP, the same number of moles of O3 gas would occupy the same volume.
Thus, the volume of 0.1 mol of O3 gas under the same STP conditions would also be 2.24 L.
