Chapter 8, Problem 63E

Interpretation Introduction

Interpretation:

The molecular formula of ethylene glycol is to be stated if the molar mass of ethylene glycol is $\text{62}\text{g}/\text{mol}$ and the percent composition is $\text{38}\text{.7\%}\text{C}$, $\text{9}\text{.74\%}\text{H}$, and $\text{51}\text{.6\%}\text{O}$.

Concept introduction:

The empirical formula of a compound gives the proportions of the elements present in the compound. The empirical formula does not give the actual number of the atoms present in the compound. The actual formula, which is the molecular formula, is a multiple of the empirical formula.
