You have 10 ml of ethanol and want to use it all to make a 10-fold dilution with water. How would you do this, including the final volume?

Add 10 mL of ethanol into a 100 mL volumetric flask. Final volume of diluted ethanol solution is 100 mL.

Explanation:

We need to use a flask of 100 mL to make a 10 times dilution of the 10 mL of ethanol that we have. To prepare this solution we have to measure with a pipet 10 mL of ethanol and place it into volumetric flask of 100 mL. Then we add destiled water to complete the volume of the final ethanol solution.

Then the final volume of the diluted solution of ethanol will be 100 mL.
