A 15.00 mL sample of an unknown monoprotic weak acid solution is titrated with 0.35 M NaOH. The initial buret reading is 0.23 mL. The phenolphthalein indicator turns the solution light pink when the buret reads 29.58 mL.

Question

A. what volume of 0.35 M NaOH was delivered?

B. How many moles of NaOH were delivered?

C. How many Moles of weak acid were present in the solution?

D. Calculate the molarity of the unknown weak acid solution

Answer 1

What about this problem troubles you. This is pretty standard; however, the buret reading may be a problem.
29.58 mL is final reading
-0.23 mL is initial reading.
----------------
29.35 ml is titration volume.

Answer 2

B. How many moles of NaOH were delivered?

C. How many Moles of weak acid were present in the solution?

D. Calculate the molarity of the unknown weak acid solution

Can you help me solve those problems as well.
