Suppose you have concentrated 12.1 M HCl
a. What volume of the concentrate is needed to make 3.0 L of 1.0 M HCl?
b. Now you have 3.0 L of 1.0 M HCl. But you dilute this further to 0.5 M. How much water should you add?
c. Will the concentrate 12.1 M, 1.0 M, or the dilute 0.5 M of HCl have the greater conductivity?

A.
B. M1V1 = M2V2
(1M)(3L)=(.5M)(V2)
V2=6L
The total volume has to be 6L, and thus, you need to add 3L more to your current 3 liters (1M solution).
(1M)(3L)=(.5M)(V2)
V2=6L
The total volume has to be 6L, and thus, you need to add 3L more to your current 3 liters (1M solution).
C.
