Chapter 11, Problem 105APP

Interpretation Introduction

Interpretation: The mass of ${\text{NH}}_3$ produced in grams should be calculated when $\text{5}\text{.0 L}$ of ${\text{H}}_{\text{2}}\text{O(g)}$ at $\text{375 °C and 725 mmHg}$ is reacted.

Concept Introduction: The ideal gas equation is combination of different gas laws such as Boyle’s law, Charles’s law, Gay-Lussac law etc. The combination of all these laws gives the ideal gas equation. The expression relating the pressure, P, volume, V with number of moles, n and temperature, T of an ideal gas is:

  $\text{PV = nRT}$

Where R is Universal gas constant.

Number of moles is defined as the ratio of given mass to the molar mass. The mathematical expression is given by:

  $\text{Number of moles =}\frac{\text{Given mass}}{\text{Molar mass}}$
