Chapter 5, Problem 168CP

Interpretation Introduction

Interpretation: The mass percent of ${\text{N}}_{\text{2}}{\text{H}}_{\text{4}}\left(g\right)$ in the original gaseous mixture is to be calculated.

Concept introduction: Mass percent of an element is defined as the ratio of mass of the element divided by the total mass of the compound. The number of moles is defined as the ratio of mass with the molecular mass of an element. The mass of an element is the amount of the substance present in an element.

To determine: The mass percent of ${\text{N}}_{\text{2}}{\text{H}}_{\text{4}}\left(g\right)$ in the original gaseous mixture.
