Answer:
1. The mass of one mole of Helium (He) is 4g. So 5 moles of Helium will be 2X5 = 10g
2. But the mass of one mole of Sodium (Na) is 23g.
3. So it is significantly higher than the total mass of Helium

Answer:
Mole of helium= molar mass of helium= 4g/mol
Mole of sodium= molar mass of sodium=23g/mol
That's why the mole of Helium is lighter than that of sodium
The atomic mass of helium is the molar mass and it is 4 u, and not *2 u*
