Question

What volume of 10M HCl must be diluted with water to get 1L of 1M HCl?

Answer 1

To obtain 1L of 1M HCl from a 10M HCl solution, you need to dilute 100mL of the 10M HCl with water to reach the final volume.

Step-by-step explanation:

To calculate the volume of 10M HCl needed to dilute with water and obtain 1L of 1M HCl, we can use the dilution equation M1 × V1 = M2 × V2, where M1 is the molarity of the concentrated solution, V1 is the volume of the concentrated solution, M2 is the molarity of the diluted solution, and V2 is the volume of the diluted solution.

Here, M1 = 10M, M2 = 1M, and V2 = 1L. Plugging these values into the dilution equation, we can solve for V1:

10M × V1 = 1M × 1L

So, V1 = (1M × 1L) / 10M = 0.1L or 100mL.

Therefore, you would need 100mL of 10M HCl to dilute with water to obtain 1L of 1M HCl solution.
