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?
