According to Avogadro's hypothesis, at the same temperature and presure equal volume of all gases contain equal number off molecules. Can it be concluded from the given statement that "all molecules have equal volume" ?

Explanation

Avogadro's hypothesis states that equal volumes of all gases under similar conditions of temperature annd pressure, contain equal number of molecules. This does not signify that actual volumes of one molecules of different gases is the same. Experimental studies have shown that molecular diameter of different gases differ from each other depending on the molecular composition of the gas. in fact, total volume of any gas (i.e., the volume of the containe in which the gas is enclosed) is equal to the sum of volume of all gas molecules and the volume of the empty space which is available for free movement of the gas molecules.
