Question

How many moles are in 4.65 x10^24 molecules of no2?

Answer 1

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

Answer 2

`n_(NO_2)=7.72molNO_2`

Step-by-step explanation:

Hello,

In this case, the following molecule-mole relation is applied by knowing that in 1 mole of molecules there
`6.022x10^(23)` molecules that is equal to the Avogadro's number, thus:

`n_(NO_2)=4.65x10^(24)molecules NO_2*(1molNO_2)/(6.022x10^(23)moleculesNO_2) \\n_(NO_2)=7.72molNO_2`

Best regards.
