#[Na^+]-=0.500*mol*L^-1#....

Explanation:

We gots sodium sulfate in solution....

#Na_2SO_4(s)stackrel(H_2O)rightleftharpoons2Na^+ + SO_4^(2-)#

The salt speciates to give two equivs of sodium ion, and one equiv of sulfate ion....and so if there is 1 mol of sulfate salt, there are 2 mol of sodium counterion....
