Chapter 3, Problem 3.106P

Interpretation Introduction

Interpretation:

The given hydrogen containing compounds (ethane, propane, benzene, ethanol, cetyl palmitate) from highest to lowest fuel value is to be ranked.

Concept introduction:

The chemical formula gives the relative moles of each element present in a compound.

The formula to calculate moles is as follows:

  $\text{Amount}\left(\text{mol}\right)=\frac{\text{mass}}{\text{molecular mass}}$        (1)

The formula to calculate the mass is as follows:

  $\text{Mass}=\left(\text{amount(mol)}\right)\left(\text{molecular mass}\right)$        (2)

Hydrogen containing fuels have a fuel value based on their mass % hydrogen.

The formula to calculate mass % is as follows:

  $\text{mass }\%=\frac{\text{total mass of element}}{\text{molar mass of compound}}\left(100\text{ \%}\right)$        (3)
