108.365mL or 108.365 cm3, this is based on the density of the ethanol which is 0.789g/mL.

What is the percent by volume of ethanol in a solution that contains 48 mL of ethanol dissolved in 144 mL of water?
Percent by Volume of Solute in Solvent = Volume Solute/ (Volume Solvent + Volume Solute) * 100% = 48/ 192 = 25%
How do you prepare 95 percent ethanol from absolute ethanol?
It is prepared by taking five volume of ethanol and dissolve in 100 ml of water .
What happens when you put frozen ethanol into liquid ethanol?
That question is too vague. I'm assuming you mean a little frozen ethanol into a larger volume of liquid ethanol. This being the case, the ethanol will melt. That's it.
Why there is no 100 ethanol?
most "absolute" ethanol used in the lab is 95% ethanol by volume,this is due to the fact the ethanol is very miscible with water so its difficult to remove all the water that is present in the atmosphere,it is possible to get 100 alcohol but it is an awkward process and generally 95 does the job just fine
If you put ethanol and water together in a beaker which would evaporate first?
Ethanol would because it has a boiling point of 78.4 C where as water has one at 100 C.Through this process breweries and wineries can distill their liquors and find the percent off ethanol (alcohol) by volume.

What is the link between percentage by volume and units of alcohol?
An UK unit of alcohol has 10 mL (8 g) ethanol. Calculate the mass or the volume of ethanol in your drinks.
Which takes up greater volume 1000 g of water or 1000 g of ethanol?
The 1000 grammes of ethanol will occupy a greater volume because its specific gravity is lower than that of water. s.g. water = ~1.0 s.g. ethanol = ~ 0.794
If a sample of ethanol has a volume of 60.0 ml what is the mass?
5
What causes volume contraction between ethanol and water?
Hydrogen bonds are formed between water and ethanol molecules, the solution become more "packed"; the density increase and the volume decrease.
What volume of ethanol has a mass of 15.5 grams?
15.5 gram ethanol x 1 mL/0.789 (density) = 19.65 mL the density of ethanol is 0.789g/mL
If 20 ml of water and 20 ml of ethanol are mixed what is the volume?
you would think 40ml but it is slightly less. 40 x 98% = 39.2ml when ethanol and water mix they are 98% of the volume
Which has a greater volume 1000g of water or 1000g of denatured ethanol?
there the same.
How to prepare 20% (v/v) of ethanol?
To prepare a 20% (v/v) solution of ethanol, you need to mix 20 mL of pure ethanol with enough solvent to make a total volume of 100 mL. This means that for every 100 mL of solution, there are 20 mL of ethanol. You can use a volumetric flask to accurately measure the volume of the ethanol and the solvent. It is important to note that the volume of the final solution may not be exactly 100 mL due to the fact that liquid volumes are not necessarily additive.
In ethanol precipitation natrium acetate is added in 0.1 volume if wrongly added the volume to 1volume what will happened?
how about the countermeasurement for that?
