answer

we first need to determine the balanced chemical reaction. which is :

Ca(OH)₂ + 2HCl > CaCl₂ + 2H₂O

now that we have the balanced reaction we can find the number of mols of HCl using the equation

C = n/v

and when we rearange the equation, we get:

n = CxV

= 0.0300M x 0.0782 L

= 0.0023 mols

we know from the balanced equation that the mol ratio of Ca(OH)₂ : HCl is 1 :2

therefor 1/2 x 0.0023 = 0.0012 mols of Ca(OH)₂ will be required

the volume then becomes:

v = n/C

= 0.0012/0.0200 M

= 0.0586L

= 58.6 mL

58.6 mL will be required to neutralize the acid
