Show all setups. Be careful with significant figures.
a. Calculate the volume of 0.450 M Ba(OH)2 which will be needed to neutralize 46.00 mL of
0.252 M HC1.
b. Find the molar concentration of a sulfuric acid solution, 35.00 mL of which neutralizes
25.00 mL of 0.320 M NaOH. (Careful! Sulfuric acid is diprotic!)
c. Calculate the “molarity of water" [H2O] in pure water at 30C. [Hint: The density of water
at 30°C is 0.9957 g/mL.]
