You have 505 mL of a 0.160 M HCl solution and you want to dilute it to exactly 0.100 M. How much water should you add
liraira [26]

This problem is providing information about the volume and concentration of HCl as 505 mL and 0.160 M respectively, and it is asking for the water that have to be added to prepare a 0.100-M solution.

In such a way, we work over the assumption of constant moles in dilution processes, so that we are able to write:

M_1V_1=M_2V_2

Which relates de volume and concentration at the beginning and end of the experiment. This means we can solve for the resulting volume of the solution as a first calculation:

V_2=\frac{M_1V_1}{M_2}\\\\V_2=\frac{0.160M*505mL}{0.100M}=808mL

Hence, the following amount of water must be added:

V_w=808mL-505mL=303mL
