Answer:
2.08 * [tex]10^{24}[/tex]
Explanation:
Avagadros number times the # of moles.
[tex]20.8*10^{23} atoms[/tex] are contained in 3.46 moles of magnesium.
One mole of a substance is equal to [tex]6.022 * 10^{23}[/tex] units of that substance (such as atoms, molecules, or ions). The number [tex]6.022 * 10^{23}[/tex] is known as Avogadro's constant.
Given:
3.46 moles of magnesium
To find:
Number of atoms=?
[tex]1 \text{ mole} = 6.022*10^{23} \text{ atoms}[/tex]
[tex]3.46 \text{ moles}= 3.46*6.022*10^{23}\\\\20.8*10^{23} \text{ atoms}[/tex]
Thus, [tex]20.8*10^{23} atoms[/tex] are contained in 3.46 moles of magnesium.
