If the volumes are additive, you would have 45 ml + 125 ml = 170 mls45 ml/170 ml (x100%) = 26.5% 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.
10ml of ethanol mix with 40ml of water find percent concentration of ethanol solution?
20%
If 20 ml of water and 20 ml of ethanol are mixed what is the volume?
you would think 40ml but it is slightly less. 40 x 98% = 39.2ml when ethanol and water mix they are 98% of the volume
The solid acid is dissolved in 100 mL of deionized water followed by 10 mL ethanol How does this added volume affect?
The added ethanol will not affect the pH whatsoever, due to the fact that ethanol cannot donate hydrogen ions or accept them. The added volume will, however, not affect the molar mass of the acid that you will report from the analyses. You use the volume of base that is used to titrate the acid to find the moles of acid and base at stoichiometric point so the added volume will not affect the molar mass.
Which has a greater volume 1000g of water or 1000g of denatured ethanol?
there the same.
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%)
How would I answer this question How many grams to 0.1 g of ethanol should be dissolved into 135 g of water to produce a 23 percent by mass ethanol solution?
The answer is 31,05 g ethanol.
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.

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.
How do you make 90 percent ethanol from 100 percent ethanol?
Add 10 parts water to 90 parts 100% ethanol.
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.
Which takes up greater volume 1000 g of water or 1000 g of ethanol?
The 1000 grammes of ethanol will occupy a greater volume because its specific gravity is lower than that of water. s.g. water = ~1.0 s.g. ethanol = ~ 0.794
How does one prepare 30 percent ethanol?
30 ml of ethanol to 70ml of distilled water.
10ml of ethanol mix with 40ml of water find percent concentration of ethanol solution?
20%
What causes volume contraction between ethanol and water?
Hydrogen bonds are formed between water and ethanol molecules, the solution become more "packed"; the density increase and the volume decrease.
