Question

How many moles are in 6.56*10^26 atoms?

Answer 1

Moles = 6.56 x 10^26 / 6.02 x 10^23 = 1089.7 moles.

Hope this helps!

Answer 2

There are 1089.34 moles in
`6.56* 10^(26)` atoms.

Step-by-step explanation:

Number of moles = n

Number of atoms = N

`N=N_A* n`

Where :

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

We have:

`N=6.56* 10^(26)`

n = ?

`6.56* 10^(26) =N_A* 6.022* 10^(23) (mol)^(-1)`

`n=(6.56* 10^(26) )/(6.022* 10^(23) (mol)^(-1))`

n = 1089.34 mol

There are 1089.34 moles in
`6.56* 10^(26)` atoms.
