i guess what your asking is if you mix equal volumes of alcohol and water will the resulting density be the same as the average of the two densities. Surprisingly the answer is no. The resultant mixture will actually be slightly denser than what you would expect by the calculation. The reason for this is that hydrogen bonds form between the compounds and pull each other closer. The relatively smaller water molecules can then reside nicely in the small spaces between the molecules.
You can perform this test and feel the bottle and see that it gets warmer when you combine the two. Meaning that this is an exothermic reaction.
Also you'll notice that if you combine equal volumes of both substances the resulting volume is slightly less than you would expect because of the water being able to fit in the small voids that the larger alcohol molecules create.

After the water is boiled its mass stays the same yes or no?
After water has been boiled, its mass will stay the same.
Which will have a greater mass - 1 L water or 1 L alcohol?
1 L water will have a greater mass than 1 L alcohol, as water is denser than alcohol.
HOW DO I CALCULATE THE PERCENTAGE BY MASS OF ETHANOL IN A MIXTURE OF ETHANOL AND WATER?
Divide the mass of the ethanol by the sum of the mass of the ethanol + that of the water and multiply by 100. Mass ethanol/(Mass ethanol + mass H2O) (x100)
All samples of pure water have the same mass?
Yes, all samples of pure water have the same mass because the mass of water is determined by its chemical composition, which consists of two hydrogen atoms and one oxygen atom. This means that regardless of the volume or container, the mass of pure water remains constant.
Does solid water have the same mass?
Need more data to answer. Are you talking about the mass of an object, neither air nor water, being the same when in the air or in the water? Yes. Are you talking about the total mass of all the air on earth compared to the total mass of all the water on earth? Definitely not.
What has a greater mass 1 liter of water or 1 liter of alcohol?
Water.
Would the blood alcohol be the same for a man and women who weight the same and drink the same?
No, even though they weigh the same men and women have a different body chemistry. Men have a higher percentage of their mass as water than men so alcohol affects them less than women.
After the water is boiled its mass stays the same yes or no?
After water has been boiled, its mass will stay the same.
Which will have a greater mass - 1 L water or 1 L alcohol?
1 L water will have a greater mass than 1 L alcohol, as water is denser than alcohol.
When water evaporates its mass decreases?
no the mass remains the same
Are there different water masses?
pure water has the same density, and the same mass
HOW DO I CALCULATE THE PERCENTAGE BY MASS OF ETHANOL IN A MIXTURE OF ETHANOL AND WATER?

How is boiling water in the law of conservation of mass?
Boiling water follows the law of conservation of mass, which states that mass cannot be created or destroyed, only transformed. When water is boiled, it is converted into water vapor, which still contains the same amount of mass as the liquid water. The total mass of the water and water vapor remains constant throughout the process.
How do you find the mass of an irregular object?
you use the water displacement test. the mass of the displaced water is equal to the mass of the object. because the density of water is one, this means that the volume of the water is equal to the mass of the object * * * * * That is only true if the body floats. Two blocks of different metals, but of the same size will displace the same volume of water. Their masses will not be the same.
What is solute and solvent of water?
Water is a single compound so it cannot be a solute and solvent at the same time.If you have a drop of alcohol in a bucket of water then water is the solvent, but if you have a drop of water in a bucket of alcohol then water is the solute.
