Question

How many moles are 3.21 x 1028 molecules of N2

Answer 1

Hello!

`\large\boxed{5.33*10^(4) moles}`

Begin by converting
`3.21 * 10^(28)` molecules to moles using Avogadro's number:

`3.21*10^(28) moles* (1 mol)/(6.02*10^(23) moles) = (3.21*10^(28) )/(6.02*10x^(23) )moles`

Simplify:

`(3.21*10^(28) )/(6.02*10x^(23) )=0.53*10^(5) = 5.33*10^(4)`

Therefore, there are
`5.33*10^(4)` moles in
`3.21*10^(28)` molecules of
`N_(2)`.
