Per cent by volume means mls of solute per 100 mls solution. So you need to know the volume of the solute and the total volume of the solution. Divide volume of solute by volume of solution and multiply by 100 to get per cent by volume.

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.
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.
How do you dilute 20 volume hydrogen peroxide to make a 3 percent solution?
20 volume is 6% solution. To make it 3% solution just add same volume of water to the original 6% solution and you have double volume of 3% solution.

How do you prepare 6n ammonium hydroxide from 30 percent solution?
To prepare 6 nM ammonium hydroxide a 30 percent solution you need to know the volume of the 30 percent solution that you have and the volume of 6nM solution you would like to make. Then use the following formula: C1V1 = C2V2 where C = concentration in moles/Liter and V = volume in liters.
How do make a percent sucrose solution?
Calculate the weight of sucrose for the desired volume and concentration of the solution.
What is the volume of alcohol present in 200.0 ml of a 55 percent by volume solution of alcohol?
The volume of alcohol is 110 mL.

What volume of 5 percent aluminum acetate solution will be needed if 120 ml of 0.05 percent solution is extemporaneously compounded for patient use?
12ml
What is another way to express the concentration of a glucose solution that is 0.01 percent by weight?
100ppb
How many grams in 1 percent solution?
A 1% solution normally contains 1 gram of active ingredient per 100 ml of solution (weight-volume percent) Could also be 1gm per 100 gms (weight-weight percent)- but normally weight-volume is used.
How much sugar is there in 100mL of a10 percent aqueous sugar solution and what is the solvent in the solution?
percent concentration = (mass of solute/volume of solution) X 100 To solve for mass of solute, mass of solute = (percent concentration X volume of solution)/100 So, mass of solute = (10% X 100mL)/100 = 10g
What solution contains the largest volume of solvent in 100mL?
3 percent alcohol
