Answer:
Number of atoms = 5.1345 x 10²³
Explanation:
Given:
Mass of sodium = 19.6
Find:
Number of atoms
Computation:
We know that atomic mass of sodium is 22.98
So,
Number of atoms = [Mass of sodium/atomic mass of sodium]Avogadro's number
Number of atoms = [19.6 / 22.98]6.02 x 10²³
Number of atoms = 5.1345 x 10²³
