Answer:
2400 mL
Explanation:
[tex]Ca + 2HCl \implies CaCl_2 + H_2[/tex]
According to this equation, the stoichiometric ratio between [tex]Ca[/tex] and [tex]HCl[/tex] for the complete reaction is 1:2.
We know that the number of moles of [tex]Ca[/tex] can be calculated using the mole formula. (number of moles = mass / molar mass)
Moles of Calcium = [tex]\frac{60}{40}[/tex] = 1.5 mol
So the moles of [tex]HCl[/tex] = [tex]1.5 \times 2[/tex] = 3.0 mol
Volume of HCl solution = Moles of HCl/ concentration of HCl
Volume of HCl solution = [tex]\frac{3}{1.25}[/tex] = 2400 mL
