<h3>
Answer:</h3>
2.5 moles
<h3>
Explanation:</h3>
<u>We are given;</u>
We are required to determine the number of moles of sodium.
- We know that, 1 mole of an element contains a number of atoms equivalent to the Avogadro's number, 6.022 × 10^23.
- That is, 1 mole of an element = 6.022 × 10^23 atoms.
Therefore;
1 mole of sodium contains 6.022 × 10^23 atoms
To get the number of moles;
= Number of atoms ÷ Avogadro's number
= 1.5 × 10^24 atoms ÷ 6.022 × 10^23 atoms/mol
= 2.49 moles
= 2.5 moles
Therefore, 2.5 moles of sodium contains 1.50 × 10^24 sodium atoms
