A 0.577g sample of a purified organic acid was dissolved in water and titrated potentiometrically. A plot of the data revealed a single end point after 23.39mL of 0.0994M NaOH had been introduced. Calculate the molar mass of the acid.
I calculated the moles of NaOH thus far:
0.02339L * 0.0994mol/L = 0.00232mol NaOH
How do I calculate the molar mass of the unknown acid?
