Well, let's see what I can do in a three minutes rush job. This is relatively simple compared to the organic chemistry that I'm doing right now, but I did learn it a year ago.
Okay, enough covering my butt.
a) Ca(OH)2 + 2HCl ------> CaCl2 + 2(H2O)
b) 0.0244 molar (half of the number of moles of HCl you titrated in multiplied by 10 because the solution was a tenth of a liter)
c) .1808 grams per 100 mL. That's the answer to b) multiplied by the molecular weight of calcium hydroxide and divided by 10.
So, how far off am I?
Edit: Whoops. I was missing a 2 in front of the water molecule.
