a. 0.00426 L

b. 1.596 L

Further explanation

The number of moles in dilution will remain constant

Can be formulated

[tex]\tt M_1.V_1=M_2.V_2[/tex]

a.

M₁=12

M₂=[tex]\tt 10^{-1.5}(pH=-log[H^+])[/tex]=0.032

V₂=1.6 L

[tex]\tt 12\times V_1=0.032\times 1.6\\\\V_1=0.00426~L[/tex]

b.

[tex]\tt 1.6-0.00426=1.596~L[/tex]
