Statement 1: Under identical conditions of temperature and pressure, 11.2 L of N₂ and 11.2 L of CO₂ contain the same number of molecules.
Statement 2: At a given temperature and pressure, the volume of a gas is decided by the number of molecules and not by their identity or size, since molecules are far apart.

Statement I is Avogadro's law applied to equal volumes: equal volumes at the same T and P contain equal numbers of molecules — correct. Statement II is correct, and it is exactly the reason the identity of N₂ vs CO₂ does not matter: with molecules far apart, the volume is governed only by their number. II explains I. Ans: (a).
