Answer 1

Answer:

12.044×10^23 atoms

or

1.2044×10^24 atoms

===================

Explanation:

Atomic mass of Na (m) = 23g

Given mass of Na (M) = 46g

Now,

We know that:

No of moles = M/m

= 46/23

= 2 moles of Sodium.

Now,

We know that:

No of entities in 1 mole of a substance = 6.022×10^23

Therefore,

No of atoms in 2 moles of Na = 2 × 6.022×10^23

= 12.044×10^23 atoms

= 1.2044×10^24 atoms
