The number of moles are in the given molecules of [tex]MgCl_2[/tex] is 0.0565 moles.
Given the following data:
- Number of [tex]MgCl_2[/tex] = [tex]3.4 \times 10^{22}[/tex] molecules
Scientific data:
- Avogadro's number = [tex]6.02 \times 10^{23}[/tex]
- The molar mass of Magnesium chloride ([tex]MgCl_2[/tex]) = 95.211 g/mol
To determine the number of moles are in the given molecules of [tex]MgCl_2[/tex]:
By stoichiometry:
1 mole of Magnesium chloride = [tex]6.02 \times 10^{23}[/tex] molecules
X mole of Magnesium chloride = [tex]3.4 \times 10^{22}[/tex] molecules
Cross-multiplying, we have:
[tex]X=\frac{3.4 \times 10^{22}}{6.02 \times 10^{23}}[/tex]
X = 0.0565 moles
