Chapter 14, Problem 88IAE

Interpretation Introduction

Interpretation:

To prepare 0.250m KOH solution what mass of either KOH or $H_{2}O$ to beadded should bedetermined.

Concept introduction:

Molarity is a concentration unit, definedto be the number of moles of solute divided by the number of liters of solution.

$\text{molarity (c) = }\frac{\text{amount of solute (in moles)}}{\text{volume of solution (in liters)}}$

Molality is a measure of the concentration of a solute in a solution in terms of amount of substance in a specified amount of mass of the solvent.

$\text{molality (m) = }\frac{\text{amount of solute (in moles)}}{\text{mass of solvent (in kilogams)}}$ $$

$\text{Density = }\frac{\text{Mass}}{\text{Volume}}$
