Chapter 8.2, Problem 8.6P

Interpretation Introduction

Interpretation:

The number of milliequivalent of ${\text{K}}^{+}$ in $550\text{ mL}$ of solution is to be calculated.

Concept introduction:

The concentration of an electrolyte is often expressed in $\text{mEq}/\text{L}$ .The conversion factor to convert milliequivalent to equivalent is as follows:

  $1\text{ mEq}={10}^{-3}\text{ eq}$

The conversion factor to convert liters to milliliters is as follows:

  $1\text{ L}=\text{1000 mL}$

To convert one system of unit to another the conversion factors are written such that the unwanted units lie in the denominator and thus are cancelled out.
