    first write down the equation for the reaction ! \[Ca(OH)2 + 2HCl \rightarrow CaCl _{2} + 2H _{2}O\] Looking a this we can ay the mole ratio of Ca(OH)2 to HCl is 1:2 So the no.of moles of HCl would be half the no of moles of Ca(OH)2 right? We can find the no. of moles of Ca(OH)2 using the given data. Use C=n/V C=Concentration n- no. of moles V= Volume Then we can find the no of moles of HCl Molarity= no. of moles of HCl/ Volume(in liters ) right ?
