Concentrated HCI is 12M. What is the molarity of an HCI solution prepared by dilluting 10ml concentrated HCI to a total volume of 250ml?

To determine the molarity of the diluted HCI solution, we can use the equation:

M1V1 = M2V2

Where:
M1 = Molarity of the concentrated HCI solution
V1 = Volume of the concentrated HCI solution
M2 = Molarity of the diluted HCI solution
V2 = Volume of the diluted HCI solution

Given information:
M1 = 12M (concentrated HCI solution)
V1 = 10ml (volume of concentrated HCI solution)
V2 = 250ml (total volume of diluted HCI solution)

We can rearrange the equation to solve for M2:

M2 = (M1 * V1) / V2

Plugging in the given values:

M2 = (12M * 10ml) / 250ml

M2 = 0.48M

Therefore, the molarity of the HCI solution prepared by diluting 10ml of concentrated HCI to a total volume of 250ml is 0.48M.
