Chapter U4, Problem C15.1RE

Interpretation Introduction

Interpretation: The use of mole and grams of contaminant in a water sample needs to be explained.

Concept Introduction: The relation between moles, mass and molar mass can be calculated with the help of given formula:

  $\text{Moles = }\frac{\text{Mass (g)}}{\text{Molar mass (g/mol)}}$

Answer to Problem C15.1RE

The calculated mole of containment provides information about their permissible limit in water which helps to determine whether the water can be used or not.

Explanation of Solution

The presence of containment in water makes the water polluted. Therefore it is necessary to check the presence of containment substances with the help of their moles and mass. The calculated moles of containment provide information about their permissible limit in water which helps to determine whether the water can be used or not.

Conclusion

The calculated moles of containment provide information about their permissible limit in water which helps to determine whether the water can be used or not.
