275 ml of active ingredient is added to 725 ml of an alcohol based solution. What is the final strength (v/v)
[275 mL/(725+275)] x 100 if you want it is %volume.
thank you
To find the final strength (v/v), we need to calculate the volume of the active ingredient in the final solution and divide it by the total volume of the solution.
First, let's calculate the volume of the active ingredient in the final solution:
Volume of active ingredient = 275 ml
Next, let's calculate the total volume of the solution:
Total volume = volume of active ingredient + volume of alcohol-based solution
Total volume = 275 ml + 725 ml
Total volume = 1000 ml
Now, let's calculate the final strength (v/v):
Final strength (v/v) = (Volume of active ingredient / Total volume) x 100
Final strength (v/v) = (275 ml / 1000 ml) x 100
Final strength (v/v) = 0.275 x 100
Final strength (v/v) = 27.5% (rounded to one decimal place)
Therefore, the final strength (v/v) is 27.5%.
