Chapter 8, Problem 47QRT

(a)

Interpretation Introduction

Interpretation:

Balanced chemical equation for the burning of octane in air has to be written.

(b)

Interpretation Introduction

Interpretation:

Volume of $C{O}_2$ generated has to be determined.

Concept Introduction:

Volume can be calculated by the equation given below:

  $\text{d = }\frac{\text{m}}{\text{V}}$

Where,

d is the density

m is the mass

V is the Volume

Number of moles can be determined using the given equation,

  $\text{n}\text{= }\frac{\text{m}}{\text{M}}$

Here, n is the number. of moles

  M is the Molar mass

    m is the Mass

Ideal gas Equation:

Any gas is described by using four terms namely pressure, volume, temperature and the amount of gas. Thus combining three laws namely Boyle’s, Charles’s Law and Avogadro’s Hypothesis the following equation could be obtained. It is referred as ideal gas equation.

  $\text{PV = nRT}$

Here,

  n is the moles of gas

    P is the Pressure

  V is the Volume

    T is the Temperature

    R is the gas constant

Unit conversion:

  $\begin{array}{l}1\text{ gal = }3.785\text{ L}\\ \\ 1\text{ L = 1000 mL}\\ \\ {\text{1 mL = 1 cm}}^3\end{array}$
