Chapter 3, Problem 3.18QP

Interpretation Introduction

Interpretation: The oxide of nitrogen $\left({\text{NO}}_{\text{2}}\text{or}{\text{N}}_{\text{2}}\text{O}\right)$ which has the larger molar mass is to be stated.

Concept introduction: The molar mass is defined as the mass of a substance which is divided by the amount of the substance. It gives the amount of a substance in grams per mole of a substance.

To determine: The oxide of nitrogen $\left({\text{NO}}_{\text{2}}\text{or}{\text{N}}_{\text{2}}\text{O}\right)$ which has the larger molar mass without calculating their molar masses.
