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 a 3 percent solution from a 40 percent solution?
This depends on the volume of the 40 percent solution you have. The question can be rewritten as: 40%a/(a+b) = 3% where a is the volume of the 40% solution, and b is the volume of water we need to add. Multiply both sides by (a+b) to get: 40%a = 3%a + 3%b Subtract 3%a from both sides to get 37%a = 3%b Divide by 3% to get: 12.3333...a = b Thus whatever the current volume is, you need to add 12.33333 times that volume in water in order to get a 3% solution.
What is the volume of alchol in 200ml of a solution if it is 20 percent?
200ml of solution x 20% of alcohol = 40ml of alcohol..
What does 42 percent vv in a whiskey mean?
It means it has 42% alcohol in a 100% solution. vv% = volume/volume % So a concentrate (v/v%) =volume solute/volume of solution * 100. So 42/100 x 100 = 42 vv%
How do you make a 1 percent solution from a 10 percent solution?
You would need to add water. The amount required is entirely dependent on how much volume you currently have. If the current volume is x then the question can be rewritten as: 10%x/(x+a) = 1% where a is the amount of water you need to add. Multiply both sides by x+a and you get 10%x = 1%x + 1%a Subtract 1%x from both sides and get 9%x = 1%a Divide by 1% and you get 9x = a Thus, to make a 1 percent solution from a 10 percent solution, you need to add 9 times the current volume of the solution in water.
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.
The concentration of alcohol and water solution is 25 percent alcohol by volume what is volume of alcohol and 200 lM of solution?
If the concentration of alcohol and water solution is 25 percent alcohol by volume, the volume of alcohol in a 200 solution is 50.
What is the formula of percent by volume and mass?
The formula for percent by volume (% v/v) is: (Volume of solute / Volume of solution) x 100 The formula for percent by mass (% w/w) is: (Mass of solute / Mass of solution) x 100
What has a percent by volume of 0.038?
A solution with a percent by volume of 0.038 contains 0.038 liters of solute dissolved in 100 liters of solution. This means that 0.038% of the total volume is the solute.
What is the difference of percent by mass and percent by volume?
Percent by mass refers to the concentration of a solute in a solution based on its mass, while percent by volume refers to the concentration based on the volume of the solution. Percent by mass is calculated as (mass of solute / mass of solution) x 100%, while percent by volume is calculated as (volume of solute / volume of solution) x 100%.
What is the volume percent concentration of hexadecimal in a solution made by mixing 50.0 ml of hexadecimal with 1.0 like of pentane?
To calculate the volume percent concentration of a component in a solution, you need to know the total volume of the solution. In this case, the total volume after mixing would be 50.0 ml + 1.0 ml = 51.0 ml. To find the volume percent of hexadecimal, you would take the volume of hexadecimal (50.0 ml) divided by the total volume of the solution (51.0 ml) and multiply by 100. This gives you a volume percent concentration of hexadecimal in the solution.
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.
What information would you need in order to convert molarity to percent by volume?
To convert molarity to percent by volume, you would need to know the molar mass of the solute and the density of the solution. With these values, you can calculate the volume of the solute in a given volume of the solution to determine the percent by volume.
What is the volume percent concentration of hexane in a solution made by mixing 50.0 mL of hexane with 1.0 L of pentane?
To calculate the volume percent concentration of hexane in the solution, you need to determine the total volume of the solution first. Mixing 50.0 mL of hexane with 1.0 L of pentane gives a total volume of 1.05 L (1000 mL + 50 mL). The volume percent concentration of hexane can be calculated as (volume of hexane / total volume) x 100. This gives (50 mL / 1050 mL) x 100 = 4.76% volume percent of hexane in the solution.

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.
What is the volume of alcohol present in 200.0 ml of a 55 percent by volume solution of alcohol?
The volume of alcohol in the solution is 110.0 ml, calculated by multiplying the volume of the solution (200.0 ml) by the alcohol by volume percentage (55%).
What is the volume percent concentration of propanol in a solution made by mixing 100 mL of propanol with 0.30 L of water?
To calculate the volume percent concentration of propanol in the solution, we first need to find the total volume of the solution. This would be the sum of the volumes of propanol and water: 100 mL + 300 mL = 400 mL. The volume percent concentration of propanol in the solution is then calculated by dividing the volume of propanol by the total volume of the solution and multiplying by 100: (100 mL / 400 mL) * 100 = 25%. Therefore, the propanol concentration in the solution is 25% (v/v).
