Answer:
The amount of ampicillin stock is [tex]V_3 = 7.5 mL[/tex]
The amount of deionized is 22.5 \ mL
Explanation:
From the question we are told that
The volume of stock solution of ampicillin in de-ionized water is [tex]V_0 = 100 mL[/tex]
The concentration (in mg ) of ampicillin in de-ionized is [tex]C_0 = 100 mg/mL[/tex]
The volume of ampicillin in deionized water to produce is [tex]V_2 = 30ml[/tex]
The concentration (in mg ) of ampicillin in de-ionized water to produce is [tex]C_2 = 25 mg/mL[/tex]
The chemical process can be mathematically represented as
[tex]V_3 100 = 30 * 25[/tex]
=> [tex]V_3 = \frac{30*25}{100}[/tex]
[tex]V_3 = 7.5 mL[/tex]
The amount of ampicillin stock is [tex]V_3 = 7.5 mL[/tex] and amount of 25 mL (30 - 7.5 = 22.5 mL ) of deionized water
