Which has more number of atoms, 100 grams of sodium or 100 grams of iron (given, atomic mass of Na = 23 u, Fe = 56 u)?
100 gm of sodium will have (Given mass / molar mass )x Avogadro's Number = (100/23) x 6.022 x 10^23 = 2.62 x 10^24 atoms 100 gms of Iron will have (100/56) x 6.022 x 10^23 = 1.07 x 10^24 atoms So 100 gms of Sodium will have more atoms.
