Explanation:
Volume of the stock solution is = ?
Initial concentration of ampicillin is = 100 mg/ml
Final volume () = 30 ml
Final concentration of ampicillin () = 25 mg/ml
Therefore, calculate the volume of given stock as follows.
=
Now, putting the given values into the above formula as follows.
=
=
= 7.5 ml
Now, we will calculate the volume of water added into it as follows.
Volume of water added =
= 30 ml - 7.5 ml
= 22.5 ml
Thus, we can conclude that required solution is 22.5 ml of deionized water.
calculating density is pretty easy if you ask me. all you gotta do is remember the formula to density.
density formula:
d is density, m is mass, and v is volume. then, just plug in the numbers into the formula when you are given a problem.
