The identity of an unknown monoprotic organic acid is determined by titration. A 0.765 g sample of the acid is titrated with 0.168 M NaOH. What is the molar mass of the compound if 37.3 mL of the NaOH solution is required to neutralize the sample? The compound is 68.8% C, 4.95% H, and 26.2% O. What is the molecular formula of the organic acid?

Different isotopes indicate that an element will have different numbers of
