Chapter 18, Problem 18.157P

Interpretation Introduction

Interpretation:

The number of ${\text{H}}^{\text{+}}$ ions when it is eliminated per week from Human urine is to be calculated.

Concept introduction:

The formula is given below for calculating concentration of ${\text{H}}_{\text{3}}{\text{O}}^{\text{+}}$,

  ${\text{[H}}_{\text{3}}{\text{O}}^{\text{+}}{\text{] = 10}}^{\text{-pH}}$

The molarity can be calculated by using following formula,

  $\text{Molarity}\text{= }\frac{\text{Moles}\text{of}\text{solute}}{\text{Volume}\text{of}\text{the}\text{solution}}$

The number of ions can be calculated by using following formula,

  $\text{Number of ions }\text{=}\text{ Moles × Avogadro}\text{number}$
