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.
All samples of pure water have the same mass?
There is a thing called heavy water. It is pure water that has a deuterium in it known as D20 instead of H20. It is pure but does not have the same mass.
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)
When sugar is dissolve in water and the water is evaporated off the mass of the sugar does what?
The mass of the sugar remains the same.
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.
All samples of pure water have the same mass?
There is a thing called heavy water. It is pure water that has a deuterium in it known as D20 instead of H20. It is pure but does not have the same mass.
What is the volume and mass of water?
The volume of water is the same as the mass of water. So if you have 100ml of water you actually have 100g of water.
When water evaporates its mass decreases?
no the mass remains the same
Which has more mass a gallon of water or sand?
They have same mass
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?
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)
When sugar is dissolve in water and the water is evaporated off the mass of the sugar does what?
The mass of the sugar remains the same.
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.
Does solid water have the same mass?
