Answer:
Explanation:
number of moles=mass/atomic mass, there N : O molar ratio can be found using number of moles. O-->n=m/Ar = 16/16 = 1 and N-->28/32 = 0.875
then divide each by smallest number.
N : O
0.875/0.875 : 1/0.875
=1 : = 1.142
which is aproximately 1:1 ratio, meaning empirical formula is NO
