Analysis of an unknown sample indicated the sample contained 0.140 grams of N and 0.320 grams of O. The molar mass of the compound was determined to be 92.02 amu. What is the molecular formula of the compound?

Question

Quizplus · Accepted Answer

The empirical formula is NO2, with a molar mass of 46.01 amu. The molecular formula is a multiple of the empirical formula. Since 92.02 amu is approximately twice 46.01 amu, the molecular formula is N2O4.
