23 g
The masses in your table represent the relative masses of the atoms of these elements. According to the table an average atom of sodium is 23/12 = 1.9 times as massive as an average atom of carbon. Thus, in order to have the same number of atoms of sodium we need a mass of carbon that is 23/12 times its mass. Since we have 12 g of carbon, we have 23/12 x 12 = 23 g sodium.
