1 mole of sodium atom= 6.022× 10^23 atoms
0.2 mole of sodium atom= 6.022× 10^23× 0.2
= 12.044 ×10^22 atoms......
0.2 mole of sodium atom= 6.022× 10^23× 0.2
= 12.044 ×10^22 atoms......

no of atoms in 1 mole = 6.022*10^23 atoms = 8 grams
no of atoms in 0.2 mole = 6.022*10^23× 0.2
= 1.204*10^23 atoms
no of atoms in 0.2 mole = 6.022*10^23× 0.2
= 1.204*10^23 atoms
