Chapter 15, Problem 120A

Interpretation Introduction

Interpretation:

The molarity of solution needs to be determined.

Concept introduction:

The molarity of a solution is the amount of solute in the solution per litre volume of the solution.

Answer to Problem 120A

The molarity of the solution was found to be 0.617mol/L

Explanation of Solution

$\begin{array}{l}Massofsolutew=25g\hfill \\ Molarweightofsolutem=81g/mol\hfill \\ Volumeofsolution=500mL\hfill \\ \begin{array}{l}MolarityofsolutionM=\frac{w\times 1000}{m\times V}\\ M=\frac{25\times 1000}{81\times 500}\\ M=0.617mol/L\end{array}\hfill \end{array}$
