Final answer:

To make a .3M HCL solution from a 1.5M HCL stock solution, you would need 0.4 liters.

Explanation:

To calculate the amount of .3M HCL that can be made from a 2: stock solution of 1.5M HCL, we need to use the dilution formula:

C1V1 = C2V2

where C1 is the concentration of the stock solution, V1 is the volume of the stock solution, C2 is the concentration of the diluted solution, and V2 is the volume of the diluted solution.

Let's plug in the values:

(1.5M)(V1) = (.3M)(2L)

From here, we can solve for V1:

V1 = (.3M)(2L) / (1.5M) = 0.4L

Therefore, 0.4 liters of .3M HCL can be made from a 2: stock solution of 1.5M HCL.
