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.

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.

200ml of solution x 20% of alcohol = 40ml of alcohol..

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%

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 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.

If the concentration of alcohol and water solution is 25 percent alcohol by volume, the volume of alcohol in a 200 solution is 50.

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

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%.

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.

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.

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.

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.

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.

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%).

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).
