Question

How many moles are contained in 3.131 × 1024 particles?

Answer 1

There are 5.199 moles in
`3.131* 10^(24)` particles.

Step-by-step explanation:

`N=n* N_A`

Where:

N = Number of particles / atoms/ molecules

n = Number of moles

`N_A=6.022* 10^(23) mol^(-1)` = Avogadro's number

We have:

N =
`3.131* 10^(24)`

n =?

`n=(N)/(N_A)=(3.131* 10^(24))/(6.022* 10^(23) mol^(-1))`

n = 5.199 moles

There are 5.199 moles in
`3.131* 10^(24)` particles.
