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

Respuesta :

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

[tex]C1V1=C2V2[/tex]

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

[tex]\begin{gathered} V1=\frac{C2V2}{C1} \\ V1=\frac{1.10M\cdot50.0ml}{4.8M} \\ V1=11.46ml \end{gathered}[/tex]

11.46ml should be used to prepare the solution.
