Hey guys, having some issues figuring how to approach some of the pre-lab questions for my chem class. Any insight on how to start these would be greatly appreciated!!

Molar Solubility and Solubility Product of Calcium Hydroxide:

Given:
1. Volume of saturated Ca(OH)2 soln (mL): 25.00
2. Molar concentration of standard HCL solution (mol/L): 0.0480
3. Buret reading, initial (mL): 1.70
4. Buret reading, final (ml) 13.90


To be solved: (If you could please check out the first 3 that I answered to double check)
5. Volume of HCL added (mL): 12.20
6. Moles of HCL added: 5.86x 10^-4
7. Moles of OH- in saturated solution: 5.86x 10^-4

8. [OH-], equilibrium (mol/L):
9. [Ca 2+], equilibrium (mol/L):
10.) Molar solubility of Ca(OH)2 (mol/L):
11.) Ksp of Ca(OH)2:



Thanks in advance!!
