A 5.314 g sample of a solid, weak, monoprotic acid is used to make a 100.0 mL solution. 30.00 mL of the resulting acid solution is then titrated with 0.09533 M NaOH. The pH after the addition of 17.00 mL of the base is 5.45, and the endpoint is reached after the addition of 45.61 mL of the base.

(a) How many moles of acid were present in the 30.00 mL sample?
mol

(b) What is the molar mass of the acid?
g/mol

(c) What is the pK_a of the acid?
