Answer:

Well #"1 mole"# of sodium is #6.022xx10^23# individual sodium atoms.

Explanation:

And #"1 mole"# of sodium, #6.022xx10^23# individual sodium atoms has a mass of #22.99*g#.

So if we have #9.04xx10^23# sodium atoms we have by definition #3/2" moles"# of sodium. So we have a mass of #3/2*molxx22.99*g*mol^-1# #=# #??g#
