Chapter 21, Problem 90IE

Interpretation Introduction

Interpretation:

The mass of octane $\left({\text{C}}_{\text{8}}{\text{H}}_{\text{18}}\left(l\right)\right)$ that must be burned in air to evolve the same quantity of energy as produced by the fusion of $1.0\text{g}$ hydrogen is to be calculated.

Concept introduction: The mass of atom is defined as the product of molar mass and number of moles. One mole is equal to the Avogadro’s number and each element consists of different molar mass that depends on the weight of its atom.

To determine: The mass of octane $\left({\text{C}}_{\text{8}}{\text{H}}_{\text{18}}\left(l\right)\right)$ that must be burned in air to evolve the same quantity of energy as produced by the fusion of $1.0\text{g}$ hydrogen.
