Q1:  You have 21.7 mL of a 0.9 M solution of A. How many moles of A do you have?

Q2: In a titration experiment, 9.3 mL of an aqueous HCl solution was titrated with 0.4 M NaOH solution. The equivalence point in the titration was reached when 9.5 mL of the NaOH solution was added. What is the molarity of the HCl solution?

Q3: In the titration of HCl with NaOH, the equivalence point is determined
a. from the point where the pink phenolphthalein turns colorless and then remains colorless on swirling.
b. from the point where the phenolphthalein turns pink and then remains pink on swirling.
c. from the point where the pink phenolphthalein first turns colorless and then the pink reappears on swirling.
d. from the point where the colorless phenolphthalein first turns pink and then disappears on swirling
