Question

which has more number of atoms 100gram of sodium or 100gram of iron (given atomic mass of Na=23u,Fe=56u)​

Answer 1

Answer:

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) ? Answer: 100 g of sodium: Number of sodium atoms = 2.62 x 1024 atoms. 100 g of iron : Number of iron atoms = 1.07 x 1024 atoms Thus, 100 g of sodium has more atoms.
