$2.77 mol$

Ok, there is one important thing to remember here, Avogadro's number ( $6.022×10^23$ ). So there is a great formula to solve this, here it is:

$x$ mol $⋅(6.022×10^23)/(1 mol)=y$ atoms

So since we already know the atoms, lets plug that in and solve!

$y$ atoms $*((1 mol)/(6.022×10^23))=x$ mol

$(1.67*10^24)*((1 mol)/(6.022×10^23))=x$ mol

$2.77=x$ mol

$2.77 mol$

Hope that helped!
