Question

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

Answer 1

Answer:

There are 1089.34 moles in $6.56\times 10^{26}$ atoms.

Explanation:

Number of moles = n

Number of atoms = N

$N=N_A\times n$

Where :

$N_A=6.022\times 10^{23} (mol)^{-1}$ = Avogadro number

We have:

$N=6.56\times 10^{26}$

n = ?

$6.56\times 10^{26} =N_A\times 6.022\times 10^{23} (mol)^{-1}$

$n=\frac{6.56\times 10^{26} }{6.022\times 10^{23} (mol)^{-1}}$

n = 1089.34 mol

There are 1089.34 moles in $6.56\times 10^{26}$ atoms.

Answer 2

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

Hope this helps!
