Question

What is the concentration of a solution made by diluting 65 mL of 6.0 M HCI to a final volume of 750 mL? Concentration: ____________ M

Answer 1

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

$C1\cdot V1=C2\cdot V2$

In this case, C1 is 6.0M, V1 is 65ml and V2 is 750ml, use these values to find C2:

$\begin{gathered} C2=\frac{C1V1}{V2} \\ C2=\frac{6.0M\cdot65ml}{750ml} \\ C2=0.52M \end{gathered}$

The final concentration is 0.52M.
