Chapter 15.15, Problem 15.32P

Interpretation Introduction

Interpretation:

The molarity of fluoride should be calculated, when solution contains $\text{1}\text{.0}\text{ppm}$ fluoride.

Concept introduction:

Parts per million:

The trace quantities of solute that present in solution is express in the term of parts per million and it is,

$\text{=}\frac{\text{No}\text{.}\text{of}\text{parts}\text{of}\text{solute}}{\text{No}\text{.}\text{ofparts}\text{of}\text{solution}}{\text{×10}}^{\text{6}}$

Molarity:

The concentration of solution is given in the term of molarity and it is calculated by division of mole of solute that present in the solution to volume of solution.

$\text{Mole}\text{=}\frac{\text{moles}}{\text{Volume}}$
