1 gram atom is the mass of 1 mole of the mono-atomic element.
so, 1 mole of N2 is equal to 2 gram-atom of N2.
14 g of Nitrogen = 1 mole of nitrogen.
Thus, 1.4 g of nitrogen will contain moles = 1.4×114 = 0.1 moles
Now, since 1 mole is equal to 2 gram-atom.
therefore, 0.1 mole would contain 0.2 gram-atom.
So, number of nitrogen atom = 0.2 × 6.022 ×1023 atoms
= 1.204 × 1023 atoms.
so, 1 mole of N2 is equal to 2 gram-atom of N2.
