Well, #"one mole of magnesium metals"# contains #6.022xx10^23# individual magnesium atoms.........

Explanation:

And thus our molar quantity is given by the quotient.........

#(5.451xx10^23*"Mg atoms")/(6.022xx10^23*"Mg atoms"*mol^-1)# #=# #"not quite a mole........."#

Can you tell us the mass of this quantity of magnesium atoms? How?
