Chapter 8, Problem 8.104CP

Summary Introduction

To determine:

The amount of solid $\text{NaOH}$ pellets used to prepare $500\text{mL}$ of a $6.0\text{M}$ $\text{NaOH}$ solution.

Introduction:

The amount or the mass $\left(\text{in}\text{g}\right)$ of any compound is calculated by the expression,

$\text{Mass}\left(\text{g}\right)=\text{Moles}\times \text{Molar}\text{mass}$

Summary Introduction

To determine:

The percent concentration of a solution of $6.0\text{M}$ $\text{NaOH}$.

Introduction:

In the case of solid solute it is convenient to express its concentration in mass/volume $\left(\text{m/v}\right)$. The concentration is expressed as,

$\text{m/v}\text{\%}=\frac{\text{Mass}\text{of}\text{solute}\left(\text{g}\right)}{\text{Volume}\text{of}\text{solution}}\times 100$
