Question

A student needs to prepare 50.0 mL of a 1.10 M aqueous H2O2 solution. Calculate the volume of 4.8 M H2O2 stock solution that should be used to prepare the solution. Volume: __________ mL

Answer 1

To solve this question, we have to use the following formula:

`C1V1=C2V2`

C1 is 4.8M, C2 is 1.10M and V2 is 50.0ml. We have to find V1:

`\begin{gathered} V1=(C2V2)/(C1) \\ V1=(1.10M\cdot50.0ml)/(4.8M) \\ V1=11.46ml \end{gathered}`

11.46ml should be used to prepare the solution.
