Answer:

7.34684 × 10^23 atoms

Explanation:

Well, one mole is basically

6.022 × 10^23 atoms. So 1.22 moles would be

6.022 × 10^23 ⋅ 1.22 atoms.

6.022 × 10^23 ⋅ 1.22 = 7.34684 × 10^23 atoms

The total number of atoms in 1.22 moles of magnesium is 7.34 × 10²³.

  • One mole of a substance is equal to 6.022 × 10²³ units of that substance (such as atoms, molecules, or ions).
  • The number 6.022 × 10²³ is known as Avogadro's number or Avogadro's constant.

Given:

1.22 moles of magnesium

[tex]1 \text{ mole}= 6.022*10^{23}\text{ atoms}\\\\1.22 \text{ moles}= 1.22*6.022*10^{23}\text{ atoms}\\\\1.22 \text{ moles}=7.34*10^{23}\text{ atoms}[/tex]

So, the total number of atoms in 1.22 moles of magnesium is 7.34 × 10²³.
