Chapter 9, Problem 9.128MP

(a)

Interpretation Introduction

Interpretation:

The molar mass of ${\text{CO}}_{\text{2}}$ produced in the reaction has to be calculated.

Concept Introduction:

Ideal gas equation is an equation that is describing the state of an imaginary ideal gas.

$\text{PV}\text{=}\text{n RT}$

Where,

P is the pressure of the gas

V is the volume

n is the number of moles of gas

R is the universal gas constant $\text{(R=0}{\text{.0821LatmK}}^{\text{-1}}{\text{mol}}^{\text{-1}})$

T is the temperature

Molar mass:

It is a physical property, which is defined as the mass of a given substance divided by the amount of substance. Unit of the kilogram is $\text{g/mol}$

$\text{molar mass}\text{=}\frac{\text{amount}\text{of}\text{mass}}{\text{molecular mass}}$

(b)

Interpretation Introduction

Interpretation:

The final temperature after the combustion inside the vessel has to be calculated.

Concept Introduction:

Number of moles:

It is a physical property, which is defined as the mass of a given substance divided by the amount of substance. Unit of the mol

$\text{number of moles}\text{=}\text{amount}\text{of}\text{mass}\times \frac{\text{molar mass}}{\text{molecular mass}}$

(c)

Interpretation Introduction

Interpretation:

The partial pressure of ${\text{CO}}_{\text{2}}$ in the vessel after the combustion reaction has to be calculated.
