Chapter 22, Problem 22.26P

Interpretation Introduction

Interpretation:

Amount of heat liberated on combustion of hydrogen and mass of oxygen consumed should be identified.

Concept introduction:
Mass of hydrogen used as fuel can be determined with the help of density which is mass per unit volume and can be shown as:

   $\text{d = m /V}$

Here,
d is density
m is mass
v is volume

Given:

Volume of hydrogen = $\text{1}\text{.45 }\times {\text{ 10}}^{\text{6}}\text{L}$

Density of hydrogen = kg /L
Heat of combustion = $\text{ - 242 kJ /mol}$
