Answer:
→One mole of calcium has more mass
Explanation:
✓Molar mass of sodium = 23g
→Mass of one mole Na = 23g
→Atomic mass of calcium = 40 u
Atomic mass of Ca = 40 ×1.6 × 10^-24 g
Mass of one atom of Ca = 6.4 × 10^-23g
→Molar mass of calcium = 40 g
→Mass of one mole of calcium = 40g
→On comparing we get mass of :
1 mol Ca > 1 mol Na > 1 atom of Ca
