#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!
