The empirical and molecular formula would be  [tex]NO_2[/tex] and  [tex]N_2O_4[/tex] respectively.

Empirical formula

The compound contains N and O.

N                                                        O

0.608/14 = 0.0434                        1.388/16 = 0.0867

Divide by the smallest.

N = 1                                             O = 2

Thus, the empirical formula would be [tex]NO_2[/tex]

To get the molecular formula:

Empirical formula mass = 14 + (16x2) = 46

n = molar mass/empirical formula mass

          = 92/46 = 2

Thus, the molecular formula would be [tex]N_2O_4[/tex]
