Find the molecular formula for a compound with an empirical formula of NO2 and a molar mass of 92 grams

Answer: N2O4

Explanation: To calculate the molecular formula we must need to get the empirical mass of the compound.

N = 14

O = 16 x 2

Empirical mass is 46

Molecular formula is equal to molecular mass over empirical mass

Substitute the values;

Molecular formula = 92 g / 46 = 2

Multiply the compound by 2

N2O4
