Volume of alcohol = 4 mL of alcohol
Volume of water required = 194 mL
<h3>What is a dilution factor?</h3>
A dilution factor is a ratio of the solute to solvent. It is used to express how much of the original stock solution is present in the total solution.
Given the following dilution to make:
obtain 200 ml of an isopropyl solution using the dilution ratio 1 : 20 of alcohol to water.
Total volume = 200 ml
Volume ratio of alcohol to solution will be 1/50 * 200
Volume of alcohol = 4 mL of alcohol
Then volume of water required = 200 m - 4 ml
volume of water required = 194 mL
In conclusion, the dilution is done using the dilution factor.
