Question

I did an experiment called Potentiometric Analyses where we titrate NaOH with a solid unknown weak acid.  Our group was told that our weak acid is diprotic.

Mass of dry, solid acid = .155g

Molar concentration of NaOH (mol/L)= 0.100 

Buret reading of NaOH, initial (mL)= 50 mL

Buret reading NaOH at stocichiometric point, final (mL)= 22.1 mL

Volume of NaOH dispensed (mL) 27.9 mL

Moles of NaOH to stoichiometric point (mol) : _____________

(I think the above answer would be 2.79 x 10-2? if yes then skip)

Moles of acid (mol) _____________

Molar mass of acid (g/mol) __________

Note: In the book it says for a diprotic acid, 2 mol of OH-, neutralizes one mole of acid.
