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.
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.
To calculate the percent by volume, add the volumes of ethanol and water together (45 mL + 125 mL = 170 mL). Then determine the percentage of ethanol in the total volume by dividing the volume of ethanol by the total volume and multiplying by 100 (45 mL / 170 mL * 100 ≈ 26.47%). Therefore, 45 mL of ethanol dissolved in 125 mL of water represents approximately a 26.47% ethanol solution by volume.
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.
The total volume of the solution is 10ml + 40ml = 50ml. The percentage concentration of ethanol in the solution is (10ml / 50ml) * 100% = 20%.
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
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.
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.
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%)
To calculate the percent by volume, add the volumes of ethanol and water together (45 mL + 125 mL = 170 mL). Then determine the percentage of ethanol in the total volume by dividing the volume of ethanol by the total volume and multiplying by 100 (45 mL / 170 mL * 100 ≈ 26.47%). Therefore, 45 mL of ethanol dissolved in 125 mL of water represents approximately a 26.47% ethanol solution by volume.
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.
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.

Absolutely, recent painstaking scientific research has showed that 70% ethanol is the same as 70% ethanol.
to save the 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.
