Answer 2

Explanation:

Number of moles of atoms =

Number of moles of atoms =Number of moles =

Number of moles of atoms =Number of moles =Number of moles of molecules =

Number of moles of atoms =Number of moles =Number of moles of molecules =Number of moles of molecules =

Number of moles of atoms =Number of moles =Number of moles of molecules =Number of moles of molecules =(i) 1 mole of molecules = Gram molecular mass.

Number of moles of atoms =Number of moles =Number of moles of molecules =Number of moles of molecules =(i) 1 mole of molecules = Gram molecular mass.(ii) 1 mole of molecules = 6.023 × 1023 molecules.
