Answer: -
N₂O₄
Explanation: -
Emperical formula = NO2
Emperical formula mass = 14 x 1 + 16 x 2 =46 g /mol
Molecular weight = 92.0 g/mol
n = [tex] \frac{Molecular weight}{Emperical Formula Weight} [/tex]
= [tex] \frac{92.0 g/ mol}{46 g/ mol} [/tex]
= 2
Molecular formula = (Emperical formula)n
= (NO₂)₂
= N₂O₄
