Chapter 4, Problem 115IAE

Interpretation Introduction

Interpretation:

Whether the given liquid is a pure alcohol or mixture of methanol and ethanol should be determined.

Concept introduction:

Alcohols reactto excess oxygen to produce carbon dioxide.

One mole of methanol and ethanol produce one and two moles of carbon dioxide respectively.

The number of moles can be calculated from mass and molar mass of the species as follows:

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

Here, m is mass and M is molar mass.
