Calculating Volume/Volume Percentage of a Solution
Calculation of V/V Percentage
15ml of alcohol is mixed in 45ml of water. Calculate the V/V percentage of the solution.
Final Answer: The volume/volume percentage of a solution is calculated by taking the volume of the solute, dividing it by the total volume of the solution, and then multiplying by 100%. In this case, the V/V percentage is 25%.
Explanation
The student is asking how to calculate the volume/volume (V/V) percentage of a solution. The V/V percentage is calculated by taking the volume of the solute (in this instance, alcohol) and dividing it by the total volume of the solution, then multiplying by 100%. So, in this case, the volume of alcohol is 15ml and the total volume of the solution (alcohol + water) is 60ml (15ml alcohol + 45ml water).
Use the following formula for solution concentration calculations: Concentration (V/V) = (Volume of solute / Volume of solution) x 100%
Plugging in our numbers: Concentration (V/V) = (15ml / 60ml) x 100%
This gives us a V/V percentage of 25%.
15ml of alcohol is mixed in 45ml of water. Calculate V/V percentage of the solution. The V/V percentage of the solution is 25%. It is calculated by dividing the volume of alcohol by the total volume of the solution and multiplying by 100%.
