Asked by sara
A 9.60 mL sample of 12.0 M HCl is used to prepare 125 mL of diluted acid. A sample of 32.4 mL of Ba(OH)2 base is exactly neutralized by 24.0 mL of dilute acid. What is the concentration of the Ba(OH)2 base? Help. I don;t know where to start.

Molarity of diluted acid:
12*(9.6/125)
next, the titration equation:
Na*Va=Nb*Vb
12*(9.6/125)*24=2*Mb*32.4
solve for molarity of base, Mb
