How many atoms in a #"quarter dozen magnesium atoms?"#

Explanation:

Two, five, four, or THREE...?

This question is precisely the same as the former...except that ONE mole #-=6.022xx10^23*mol^-1#...

And so we take the PRODUCT....#1/4*molxx6.022xx10^23*mol^-1#

#~=1.5xx10^23*"magnesium atoms"#...what is the mass of this quantity?
