Chapter 3, Problem 3.119SP

Interpretation Introduction

Interpretation:

The efficiency of the given process should be determined when $1.000gallon$ octane is burned and a total mass of $11.53\text{kg}$$\text{CO}$,${\text{CO}}_2$ and ${\text{H}}_2\text{O}$ are produced.

Concept Introduction:

• Balanced chemical equation of a reaction is written according to law of conservation of mass.
• Mole ratio between the reactant and a product of a reaction are depends upon the coefficients of reactant and product in a balanced chemical equation.
• Equation for Number of moles of a substance, from its given mass is,

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

• Number of grams of a substance from its number of moles is,

      $\text{Number of moles}\text{×}\text{Molecular}\text{mass in grams}\text{=}\text{Number}\text{of}\text{grams}$
