Neutralization Reaction Molarity Calculations:

For example: What is the molarity of a Ca(OH)2 solution if .032 L of the solution is exactly neutralized by .015 of a 0.56 M HCl?

How do I solve- I am unsure where to begin.

Balance the equation:

Ca(OH)2 + 2HCl >> CaCl2 + 2H20

ok, it takes two moles of HCl for each mole of Calcium hydroxide.

moles Ca(OH)=Molarity*volume and you don't know M
moles HCl= molarity*Volume=.56*.015

so, the 2* molesCa(OH)2= moleHCL
and you can then find molarity of the calcium hydroxide.
