Not very many moles....

Explanation:

Take the quotient... $\frac{2.57 \times 10^{11} \cdot atoms}{6.022 \times 10^{23} \cdot atoms \cdot m o l^{- 1}} = ? ? \cdot m o l$ $(2.57xx10^11*"atoms")/(6.022xx10^23*"atoms"*mol^-1)=??*mol$

You should also be able to tell us the mass of this quantity IF we SPECIFY the atom. $How so?$ $"How so?"$
