A student prepares a solution for titration by adding a 10.00 mL aliquot of a solution saturated with Ca(OH)2 at 82.9°C to 25.0 mL of deionized water. This solution is titrated with a standardized 0.01252 M HCI solution. The equivalence point is observed after 17.94 mL of the HCl solution has been added. use this data to answer the questions below. Calculate the moles of OH- in the 10.00ml sample. (Hint, moles of OH- at the equivalence point = moles HCI) Your answer should have 4 sig figs. Enter answers in scientific notation using E, as 1.234 E-2 for example. Answer: 8.984e-3 Calculate the moles of Ca2* in the 10.00ml sample. (See equation 1 in the procedure) Your answer should have 4 sig figs. Answer: 0.000032
