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

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 $3/2*molxx22.99*g*mol^-1$ $=$ $??g$

What mass is associated with 9.04xx10^239.04xx10^23 individual sodium atoms?
