Chapter 20, Problem 5PS

Interpretation Introduction

Interpretation:

The concentration of $\text{CO}$ in $\text{mg/}\text{}\text{L}$ and by mass should be determined.

Concept introduction:

• Parts per million (ppm): It is one of the important concentration expressing terms, and which describes grams of solute per million grams of total solutions.

  $\begin{array}{l}\text{ppm}\text{=}\frac{\text{Mass}\text{of}\text{solute}}{\text{Mass}\text{of}\text{solution}}{\text{×10}}^{\text{6}}\\ \\ \text{1}\text{ppm}\text{=}\text{1}\text{mg/L}\end{array}$

• Mass of a substance from its number of moles is,

  $\text{Number of moles}\text{×}\text{Molecular}\text{mass in grams}\text{=}\text{Mass}\text{of}\text{substance}$
