We let the empirical formula for the compound compost of sodium and chlorine as NaxCly. The molar mass of the empirical equation is,

23x + 35y

The percentages,

Na: 0.40 = 23x / (23x + 35y)

Cl: 0.60 = 35y / (23x + 35y)

The values of x and y from the equation are,

x = 1 and y = 1

Thus, the answer is that the empirical formula is NaCl.
