Vedclass · Answer

(C) The Avogadro constant is defined as the number of constituent particles (atoms,molecules,or ions) per mole of a given substance.By definition,one mole of any substance contains $6.022 	imes 10^{23}$ particles.Since one gram molecular mass of a substance is equivalent to one mole,it contains exactly $6.022 	imes 10^{23}$ molecules.Therefore,the correct definition is the number of molecules present in one gram molecular mass of a substance.
