most "absolute" ethanol used in the lab is 95% ethanol by volume,this is due to the fact the ethanol is very miscible with water so its difficult to remove all the water that is present in the atmosphere,it is possible to get 100 alcohol but it is an awkward process and generally 95 does the job just fine
What else can I help you with?
How do you make 90 percent ethanol from 100 percent ethanol?
Well, darling, you can't make 90% ethanol from 100% ethanol because, sweetie, 100% means it's already pure ethanol. You can dilute it with a calculated amount of water to get to 90%, but you ain't changing that 100% ethanol into something else. So, mix it up with water like a fancy cocktail and voilà, you've got yourself some 90% ethanol.
What are the solvent and solute in a solution containing 100 grams of ethanol and 3 grams of sucrose?
Ethanol is the solvent and sucrose is the solute.
How do you prepare 95 percent ethanol from absolute ethanol?
To prepare 95% ethanol from absolute ethanol, you would need to dilute the absolute ethanol with a calculated amount of distilled water. Since absolute ethanol is 100% pure, you can use the formula C1V1 = C2V2, where C1 is the initial concentration (100%), V1 is the volume of absolute ethanol, C2 is the desired concentration (95%), and V2 is the final volume of the diluted solution. By rearranging the formula and solving for V1, you can determine the volume of absolute ethanol needed to achieve a 95% ethanol solution when mixed with water.
What is the percent by volume of ethanol in a solution that contains 48 mL of ethanol dissolved in 144 mL of water?
The total volume of the solution is 48 mL + 144 mL = 192 mL. The percent by volume of ethanol is calculated as (volume of ethanol / total volume of solution) * 100%. Plugging in the values, we get (48 mL / 192 mL) * 100% = 25%. So, the solution contains 25% ethanol by volume.
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.
How do you make 90 percent ethanol from 100 percent ethanol?
Well, darling, you can't make 90% ethanol from 100% ethanol because, sweetie, 100% means it's already pure ethanol. You can dilute it with a calculated amount of water to get to 90%, but you ain't changing that 100% ethanol into something else. So, mix it up with water like a fancy cocktail and voilà, you've got yourself some 90% ethanol.
What state is ethanol at -100 degrees?
Ethanol would be in a solid state (frozen) at -100 degrees Celsius.
What state is ethanol at 100 degrees celsius?
Ethanol is a liquid at 100 degrees Celsius, as its boiling point is 78.37 degrees Celsius. At 100 degrees Celsius, ethanol would be in its gaseous state.
What is the state of ethanol at 100 degrees celsius?
At 100 degrees Celsius, ethanol is in its liquid state. Ethanol boils at a higher temperature of 78.4 degrees Celsius, so at 100 degrees Celsius it would be in a liquid state.
How do you dissolve LY2183240?
100% in ethanol
Approximately how many kcalories from ethanol are contained in one standard drink of vodka or rum?
There are about 100 kcalories from ethanol in a standard drink of vodka.
HOW DO I CALCULATE THE PERCENTAGE BY MASS OF ETHANOL IN A MIXTURE?
First, determine the mass of ethanol in the mixture by dividing the mass of ethanol by the total mass of the mixture. Then, multiply the result by 100 to get the percentage by mass of ethanol in the mixture. For example, if a mixture contains 20g of ethanol in a total mass of 100g, the percentage by mass of ethanol would be (20g / 100g) * 100 = 20%.
Is 100 percent ethanol a pure substance?
Yes, as long as a substance is 100% (purity), it is considered as a pure substance. But logically, there is no such thing as a pure substance.
What are the solvent and solute in a solution containing 100 grams of ethanol and 3 grams of sucrose?
Ethanol is the solvent and sucrose is the solute.
What is the percent volume of ethanol?
The percent volume of ethanol in a solution is the volume of ethanol divided by the total volume of the solution, multiplied by 100. It is commonly used to express the concentration of ethanol in alcoholic beverages or solutions.
How do you make 100 percent of ethanol from 80 percent ethanol?
To increase the concentration of ethanol from 80% to 100%, you can use a process called distillation. By distilling the 80% ethanol solution, you can separate the ethanol from the water and other impurities, resulting in a higher concentration of ethanol.
How do you prepare 95 percent ethanol from absolute ethanol?
To prepare 95% ethanol from absolute ethanol, you would need to dilute the absolute ethanol with a calculated amount of distilled water. Since absolute ethanol is 100% pure, you can use the formula C1V1 = C2V2, where C1 is the initial concentration (100%), V1 is the volume of absolute ethanol, C2 is the desired concentration (95%), and V2 is the final volume of the diluted solution. By rearranging the formula and solving for V1, you can determine the volume of absolute ethanol needed to achieve a 95% ethanol solution when mixed with water.
