A pharmacy technician has been given 100 milliliters of a 25% solution and been asked to dilute the solution to 500 milliliters with sterile water. she has also been asked to label the solution. what percentage should appear on the label?
Percentage
by volumeĀ is the amount of a component in a mixture per 100 units of volume of the
total mixture. To solve this we use the
equation,Ā
M1V1 = M2V2
where M1 is the concentration of the stock solution, V1 is the
volume of the stock solution, M2 is the concentration of the new solution and
V2 is its volume.
