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?

Answer asap need by wednesday morning explain how a buffer works, using an ethanoic acid/sodium ethanoate system including how the system resists changes in ph upon addition of a small amount of base and upon addition of a small amount of acid respectively. include the following calculations in your i. calculate the ph of a solution made by mixing 25cm3 0.1m ch3cooh and 40cm3 0.1m ch3coo-na+. [ka = 1.74 x 10-5 m] ii. calculate the ph following the addition of a 10cm3 portion of 0.08 m naoh to 500cm3 of this buffer solution. iii. calculate the ph following the addition of a 10cm3 portion of 0.08 m hcl to 200cm3 of the original buffer solution.
