Verified Answer :

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

Hope this helps!

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.
