How much percentage of ethanol is there in wine?
usually 9 to 13 percent by volume. 11.5 percent is average. fortified wines are higher. alcohol by volume times 0.8 equals alcohol by volume.
What are the mole fraction and molality of ethanol -C2H5OH in an aqueous solution that is 45.0 percent ethanol by volume-The density of water is 1.00g per mL and that of ethanol is 0.789 grams per mL?
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.
What is the difference of percent by mass and percent by volume?
Percent per mass is exprimed in g/Kg, mg/kg, µg/kg, etc. Ex.: An ore contain 10 mg gold/kg ore. Percent per volume is exprimed in volume to volume. Ex.: Vodka contain 40 volumes of ethanol/100 volumes of liquid.
What volume of ethanol 96 percent should be added to 500 ml of 70 percent ethanol such that when the mix is made to 2.5l with water the final conc of ethanol is 55 percent?
First calculate how much ethanol you need in the final solution. 55% X 2.5l = 1.375l Then calculate how much ethanol you already have in the solution. 0.5l X 70% = 0.35l Now take the difference between those two numbers as the extra amount needed. 1.375l - 0.35l = 1.025l Now correct for the fact that you are adding only 96% ethanol. 1.025l / 96% = 1.068l Answer: 1.068l
What is the percent by volume of 45 mL of ethanol dissolved in 125 of water?
If the volumes are additive, you would have 45 ml + 125 ml = 170 mls45 ml/170 ml (x100%) = 26.5% by volume
What is the percent by volume of ethanol in a solution that contains 48 mL of ethanol dissolved in 144 mL of water?
Percent by Volume of Solute in Solvent = Volume Solute/ (Volume Solvent + Volume Solute) * 100% = 48/ 192 = 25%
How do you prepare 95 percent ethanol from absolute ethanol?
It is prepared by taking five volume of ethanol and dissolve in 100 ml of water .
How does one prepare 95 percent of ethanol from 100 percent?
Find the volume of the 100% ethanol Add 1/19 of water to the volume (if it is like 190ml, add 10ml of water since 190/200=95%)

What is the percentage of volume?
Volume percent (v/v %) is defined as: volume percent = [(volume of solute) / (volume of solution)] x 100% Volume percent is handy when preparing solutions of liquids. Concentration of a solution can be stated in volume percentages. Be aware that volume of solution is in formula denominator, not volume of solvent. Thus to get 10% v/v solution of ethanol in water you can take 10 ml of ethanol and add enough water to have total 100 ml of resulting solution. It is worth to mention volumes of solute and solvent cannot be simply added to get volume of solution. For instance if you add 10 ml of ethanol to 90 ml of water the volume of the solution will be less than 100 ml.

Is 70 percent ethanol the same with 70 percent ethanol?
Absolutely, recent painstaking scientific research has showed that 70% ethanol is the same as 70% ethanol.
How do you make 90 percent ethanol from 100 percent ethanol?
Add 10 parts water to 90 parts 100% ethanol.
Why use the 70 percent ethanol?
to save the ethanol
What is the total volume of 70 percent ethanol from 1600ml ethanol?
If I understand you correctly, we are trying to find the volume of 70% of 1600 ml of ethanol. That said: here is how you do it:1. Change 70% into a decimal. You do this by moving the decimal point two places to the right. This would turn 70 into .702. Multiply .70 x 1600.3. The answer is: 1120mL.
If you put ethanol and water together in a beaker which would evaporate first?
Ethanol would because it has a boiling point of 78.4 C where as water has one at 100 C.Through this process breweries and wineries can distill their liquors and find the percent off ethanol (alcohol) by volume.
