Question

answer it correct.. ​

Answer 1

Answer:

Given

Atomic mass of Na = 23 u

Atomic mass of Fe = 56 u

Then, gram atomic mass of Na = 23 g

Now, 23 g of Na contains = 6.022 x 10^23 g number of atoms

Thus, 100 g of Na contains = 6.022 x 10^23 / (23 x 100 number of atoms)

100 g of Na contains = 2.6182 x 10^24 number of atoms

Then, gram atomic mass of Fe = 56 g

Now, 56 g of Fe contains = 6.022 x 10^23 g number of atoms

Thus, 100 g of Fe contains = 6.022 x 10^23 / (56 x 100 number of atoms)

100 g of Fe contains = 1.0753 x 10^24 number of atoms

Therefore, 100 grams of sodium contains more number of atoms than 100 grams of iron.
