Summary Introduction

To determine:

The volume of $12\%$ stock solution required to prepare the order of $1.0\text{L}$ of $0.5\%$ benzalkonium chloride antiseptic.

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,

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

The dilution equation of the solution is expressed as,

$C_{\text{initial}}\times V_{\text{initial}}=C_{\text{Final}}\times V_{\text{Final}}$
