320ml of active ingredient is added to 680ml of an alcohol based solution. What is the final strength (v/v)? ___
Use your other posts as a template.
% v/v is mL solute/total mL and you assume the volumes are additive (which isn't the usual case).

To find the final strength (v/v), we need to calculate the ratio of the volume of the active ingredient to the total volume of the solution.
First, we need to find the total volume of the solution after adding the active ingredient. This can be calculated by adding the volumes of the active ingredient and the alcohol-based solution:
Total volume of solution = volume of active ingredient + volume of alcohol-based solution
Total volume of solution = 320ml + 680ml
Total volume of solution = 1000ml
Now, we can find the final strength (v/v) by dividing the volume of the active ingredient by the total volume of the solution and multiplying by 100:
Final strength (v/v) = (volume of active ingredient / total volume of solution) * 100
Final strength (v/v) = (320ml / 1000ml) * 100
Final strength (v/v) = 32%
Therefore, the final strength (v/v) of the solution is 32%.
