if need to do some tests by specific gravity bottle, weighing balance or whatever else, what tests to be done? and the procedures?

The partial molar volumes as a function of composition have to be obtained experimentally. This allows the volume of any mix to be found. There is no way to do this by pure calculation as it depends on how well the molecules of the two liquids "fit together" in solution. The experiment is fairly labourious it uses density bottles which are small bottles that are calibrated to contain a specific volume. Various compositions are put in the bottle and it is then weighed to find the density of the solution.

Unfortunately, there is no quick and simple way to calculate the final volume from the mixture of two miscible liquids. In this case I am assuming that the alcohol (methanol, ethanol, propanol) will dissolve in the water.
If you have a larger molecule alcohol that will not dissolve completely in water, then the final volume will most likely be very close to 2.0 liters.

because alcohol and water are miscible the volumes don't quite add up. it just is except and move on. normally you don't have to do calculations based on unless you're diluting drinks.

seems like it would equal 2 liters
