Work done to eject the sodium ion from interior of the cell is given by the product of charge and Potential difference between inner and outer surface of the cell.

$W=q\times V$

Charge on sodium ion $q=1.6\times 10^{19}\ C$

$V=\frac{W}{q}$

$V=\frac{1.35\times 10^{-20}}{1.6\times 10^{19}}$

$V=0.0718\ V$
