Answer:
N2O5
Explanation:
Empirical formular is the simplest formular of a compound and shows the atoms present in simple rations.
Molecular formular on the other hand shows the exact number of atoms of element present in a compound.
To obtain molecular formular from empirical formular;
(Empirical formular)n = Molar mass
where n is a simple integer.
(N2O5)n = 108 g/mol
Molar mass of N2O5 = 108 g/mol
(108) n = 108
n = 108 / 108 = 1
Molecular formular = (Empirical formular)n
Molecular formular = (N2O5)*1 = N2O5
In this question, the empirical formular is the same as the molecular formular
