Atoms and molecules are so small in size that it is neither possible to count them individually nor possible to determine their mass. These are counted collectively in terms of Avogadro's number. The mass of Avogadro's number of atoms and molecules is known as gram atomic mass and gram molecular mass respectively. The volume occupied by Avogadro's number of molecules of a gas or vapours is known as molar volume. If 3.01 xx 10^(20) molecules are removed from 98 mg of H_(2)SO_(4) , then the number of moles of H_(2)SO_(4) left will be
