Question

How do you prepare 100mL of 0.5mL using your stock solution?

Answer 1

The concentration of the solution is 0.005M

Step-by-step explanation

Given that

The concentration of the stock solution is 1M

The volume of the stock solution to be diluted is 5mL

The final volume of the solution is 100mL

Follow the steps below to find the concentration of the resulting solution

Apply the dilution formula

C1 V1 = C2 V2

Substitute the given data into the above formula

`\begin{gathered} 1\text{ }*\text{ 5 = C2 }*\text{ 100} \\ 0.\text{5 = 100C2} \\ \text{ Divide both sides by 100} \\ \text{ }\frac{\text{ 0.5}}{\text{ 100}}\text{ = C2} \\ \text{ C2 = 0.005M} \end{gathered}`

Therefore, the concentration of the solution is 0.005M
