What volume of a 1.70 M HCl solution should you use to prepare 2.60 L of a 0.200 M HCl solution?

= 0.306 L

Explanation:

Using the dilution formula

M1V1 = M2V2

where M1 is the initial concentration and V1 is the initial volume, while M2 is the new concentration and V2 is the new volume.

1.70 * V1 = 2.6 L * 0.200

V1 = (2.6*0.20) / 1.7

= 0.306 L
