Calculate the number of moles of Ca(OH)2
(aq) needed to react completely with 125 mL of 6.00
M HCl(aq).

It doesnt give any stoichometric coefficients so how are you meant to do this?

Using the titration equation:

moles Ca(OH)2 * Normality Ca(OH2)=molesHCl*normalityHCL

moles Ca(OH)2 * 2N=.124L*6moles/liter * 1N

molescalciumhydroxide=1/2 * .124 * 6
