1mole =6*10^23
So divided 4.65*10^24 by 6*10^23=7.75

Answer:

[tex]n_{NO_2}=7.72molNO_2[/tex]

Explanation:

Hello,

In this case, the following molecule-mole relation is applied by knowing that in 1 mole of molecules there [tex]6.022x10^{23}[/tex] molecules that is equal to the Avogadro's number, thus:

[tex]n_{NO_2}=4.65x10^{24}molecules NO_2*\frac{1molNO_2}{6.022x10^{23}moleculesNO_2} \\n_{NO_2}=7.72molNO_2[/tex]

Best regards.
