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

mL x M = mL x M

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

M1V1 = M2V2

Where:
M1 = Initial molarity of the solution (12M)
V1 = Initial volume of solution (10ml)
M2 = Final molarity of the solution (unknown)
V2 = Final volume of solution (250ml)

We need to find M2, so we can rearrange the equation to solve for M2:

M2 = (M1 * V1) / V2

Now let's substitute the values into the equation:

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

M2 = 0.48M

Therefore, the molarity of the diluted HCI solution is 0.48M.
