<u>Answer:</u>
2400 mL
<u>Explanation:</u>

According to this equation, the stoichiometric ratio between
and
for the complete reaction is 1:2.
We know that the number of moles of
can be calculated using the mole formula. (<em>number of moles = mass / molar mass</em>)
Moles of Calcium =
= 1.5 mol
So the moles of
=
= 3.0 mol
<em>Volume of HCl solution = Moles of HCl/ concentration of HCl</em>
Volume of HCl solution =
= 2400 mL
