A 10.00 mL sample of a Ca(OH)2 solution is diluted to 250.0 mL total volume. A 25.0 mL sample of the 250.0 mL solution is titrated with 0.256 M HCl solution, and the equivalence point is found to be 34.68 mL. What is the concentration of Ca(OH)₂ in the original solution (before diluting to 250.0 mL)?
