Chapter 6, Problem 97IAE

Interpretation Introduction

Interpretation:

The total gas pressure in atm should be calculated in the flask at temperature 25 degree Celsius when ${\text{NH}}_{\text{4}}{\text{NO}}_{\text{3}}$ is decomposed completely.

Concept introduction:

The thermal decomposition of solid ammonium nitrate forms two gaseous products that aredinitrogen oxide and water vapor. The total pressure of gaseous product can be calculated with the help of ideal gas equation and the moles of gaseous product are calculated from the mole concept.

The ideal gas law can be written as:

$\text{PV = nRT }$

Where, P = pressure

V = volume

n = number of moles (ratio of mass to the molar mass)

R = Universal gas constant

T = temperature
