Chapter F, Problem G.7E

Interpretation Introduction

Interpretation:

The mass of each component in the solution that is $\text{510}\text{g}$ of aqueous solution containing $5.45\%$ of ${\text{KNO}}_{\text{3}}$ by mass has to be calculated.

Concept Introduction:

Molarity of the solution is defined as the number of moles of solute that is dissolved in the volume of solution in liters.  Unit of molarity is $\text{mol}\cdot {\text{L}}^{-1}$.  The equation for molarity is given as follows;

    $\text{Molarity (M)}=\frac{\text{Amount of solute in moles}}{\text{Volume of solution in liters}}$

Molar concentration of solute is used for calculating the amount of solute in solution as given below;

    $n=c\times V$

The equation to calculated the mass of solute dissolved in solution is given as follows;

    $m=cMV$

Where,

    $m$ is the mass of solute.

    $c$ is the concentration of solution.

    $M$ is the molar mass of solute.

    $V$ is the volume of solution.
