If the volumes are additive, you would have 45 ml + 125 ml = 170 mls45 ml/170 ml (x100%) = 26.5% 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.

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?
First, calculate the volume percentages of ethanol and water in the solution. Since we know the density of both solvents, convert the percentages to mass (using density and volume). Then calculate the mole fraction of ethanol by dividing the moles of ethanol by the total moles of all components in the solution. Finally, calculate molality using the moles of solute (ethanol) and the mass of the solvent (water).
10ml of ethanol mix with 40ml of water find percent concentration of ethanol solution?
The total volume of the solution is 10ml + 40ml = 50ml. The percentage concentration of ethanol in the solution is (10ml / 50ml) * 100% = 20%.
Which has a greater volume 1000g of water or 1000g of denatured ethanol?
1000g of water has a greater volume than 1000g of denatured ethanol because water is denser than ethanol. This means that water occupies less space per gram compared to ethanol.
What colour will sodium chloride turn when dissolved in ethanol water and chloroform?
Sodium chloride will not change color when dissolved in ethanol, water, or chloroform. It will form a clear solution in each solvent because NaCl is a colorless salt that does not have any inherent color.
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?
Let x be the volume of 96% ethanol added. Initial ethanol in 500 ml of 70% ethanol = 0.7(500 ml) = 350 ml Final volume of ethanol in 2.5 L of 55% ethanol = 0.55(2500 ml) = 1375 ml 350 ml + 0.96x = 1375 ml Solving for x, we get x = 1125 ml of 96% ethanol to be added.
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.
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 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.
10ml of ethanol mix with 40ml of water find percent concentration of ethanol solution?
The total volume of the solution is 10ml + 40ml = 50ml. The percentage concentration of ethanol in the solution is (10ml / 50ml) * 100% = 20%.
Which has a greater volume 1000g of water or 1000g of denatured ethanol?
1000g of water has a greater volume than 1000g of denatured ethanol because water is denser than ethanol. This means that water occupies less space per gram compared to ethanol.
How do you prepare 95 percent ethanol from absolute ethanol?
To prepare 95% ethanol from absolute ethanol, you can mix 95 mL of absolute ethanol with 5 mL of distilled water. This will dilute the absolute ethanol to the desired concentration. Make sure to mix the solution thoroughly to ensure uniform concentration.
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.
What are the example of Solutions if the solvent is liquid?
Examples of solutions with a liquid solvent include saltwater (water as the solvent with salt dissolved in it), vinegar (acetic acid dissolved in water), and ethanol (alcohol dissolved in water).
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.
