Chapter 9, Problem 72E

Interpretation Introduction

Interpretation:

The mass percentage of $\text{C}$ , $\text{H}$ and $\text{O}$ in a compound is given. The molecular formula, molar mass and Lewis structure of the unknown acid is to be identified.

Concept introduction: Mass percent of a component is defined as the mass of that component in $100\text{g}$ of mixture.

Lewis structures, also known as Lewis dot structures, are the diagrams that show bonding between various atoms of a molecule. The valence electrons around an atom are shown by dots. Bonds between atoms are shown by lines and the lone pair of electrons is shown by a pair of dots.

To determine: The molecular formula, molar mass and Lewis structure of the unknown acid.
