To calculate the new molarity when 250 mL of water is added to a solution, you can use the formula:

M1V1 = M2V2

Where: M1 = initial molarity V1 = initial volume M2 = final molarity V2 = final volume

Given: M1 = 0.251 M (initial molarity of HCl) V1 = 125 mL (initial volume of HCl) V2 = V1 + 250 mL (final volume after adding water)

Substituting the values into the formula:

(0.251 M)(125 mL) = (M2)(125 mL + 250 mL)

Solve for M2:

M2 = (0.251 M * 125 mL) / (125 mL + 250 mL)

M2 = (0.251 * 125) / 375

M2 ≈ 0.0837 M

Therefore, the new molarity of the solution after adding 250 mL of water is approximately 0.0837 M.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
