Interpretation Introduction

Interpretation:

The number of equivalents that are present in $205\text{g}$ of $\text{HI}$ is to be calculated.

Concept introduction:

In a chemical reaction, one equivalent of an acid is defined as the quantity that yields one mole of hydrogen ion. One equivalent of base is defined as the quantity that reacts with one mole of hydrogen ion. The number of equivalents can be calculated by using the fractional form for equivalent mass, the molar mass over the number of equivalents per mole.
