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)

How to obtain pure water and ethanol from a mixture of sea water and ethanol?
You would use distillation, in which the ethanol and water will boil at different temperatures.
Will letting water-sugar-yeast mixture ferment for long time affect the quantity of ethanol produced?
Letting a water, sugar, and yeast mixture ferment for a long time does not affect the quantity of ethanol produced.
Is ethyl alchohol a pure substance or mixture?
It is a pure substance.Added:Chemically speaking alcohol is meant to be ethanol, which is a pure compound with formula CH3CH2OH, it definitely is not a mixture, except when 'dissolved' in water (most stable solution: 4% water + 96% ethanol. (This is what you get when buying a bottle pure ethanol)
What is the chemical formula for whiskey?
Whiskey is mainly a mixture of ethanol (40 %) and water.
What is an example of a mixture that can be separated by evaporation?
Ethanol and water. Ethanol would evaporate at around 70 deg Celsius, water around 100 Celsius.
Is the mixture of ethanol in water a heterogeneous or homogeneous mixture?
The mixture water-ethanol is homogeneous.
What are the chemicals that are present in the mixture of ethanol and water?
Of course, these substances are ethanol and water.
What conditions are needed to make ethanol from ethene and steam?
Heating a mixture of ethanol and water would produce a mixture of water vapor (steam) and ethanol vapor. Depending on the composition of the mixture, there could be more ethanol vapor than steam in the resulting gas mixture.
How to obtain pure water and ethanol from a mixture of sea water and ethanol?

If a water ethanol mixture is distilled which will be collected first?
The ethanol will be distilled first and the water stays in the flask
How do you collect ethanol if it is in a mixture with water?
Distillation. Ethanol can be easily collected from water using distillation up to 97% purity.
Can steam distillation of ethanol be done using a mixture of ethanol and water?
I dont think so because ethanol, containing an OH group is readily soluble in water.
What is liquors density?
Since liquor is a mixture of mostly wafer and ethanol, you need to do a weighted average between them. Ethanol's density is about 80% of water's by the way. It comes out to: 1 - (.2x/100), where x is the percentage of alcohol in the drink your drinking.
Is alcohol a substance or a mixture and what kind?
mixtureAdded:Chemically speaking alcohol is meant to be ethanol, which is a pure compound with formula CH3CH2OH, it definitely is not a mixture, except when 'dissolved' in water (most stable solution: 4% water + 96% ethanol. (This is what you get when buying a bottle pure ethanol)
