15.5 gram ethanol x 1 mL/0.789 (density) = 19.65 mL the density of ethanol is 0.789g/mL
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
there the same.
The mole fraction and molality of ethanol -C2H5OH in an aqueous solution that is 45.0 percent ethanol by volume and the density of water is 1.00g per mL that of ethanol is 0.789 grams per mL and 70/18. A mole fraction in chemistry is the amount that is divided by the total amount of all constituents.
Divide by the density of ethanol.Assuming that it is a total mass of 60.354 grams, and the density of ethanol is 0.789 grams per cm3 (or grams per mL), then the volume of that much ethanol is:60.354 grams ÷ 0.789 grams/mL = 76.494 mL
495g = 17.46oz
495g = 17.5oz
Percent by Volume of Solute in Solvent = Volume Solute/ (Volume Solvent + Volume Solute) * 100% = 48/ 192 = 25%
It is prepared by taking five volume of ethanol and dissolve in 100 ml of water .
108.365mL or 108.365 cm3, this is based on the density of the ethanol which is 0.789g/mL.
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.
An UK unit of alcohol has 10 mL (8 g) ethanol. Calculate the mass or the volume of ethanol in your drinks.

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
15.5 gram ethanol x 1 mL/0.789 (density) = 19.65 mL the density of ethanol is 0.789g/mL
Hydrogen bonds are formed between water and ethanol molecules, the solution become more "packed"; the density increase and the volume decrease.
