A 0.400g sample of an unknown monoprotic acid is dissolved in water and titrated with a 0.150 M solution of NaOH. The equivalence point was determined to have a pH of 8.96 and require a NaOH volume of 26.14 mL. What is the molar mass of the unknown acid?

Explanation:

12.036

in 1783 cavendish was working with his hydrogen gas and found that when he burned it and condensed the vapor it was water. this was very significant since it disproved the greek theory of elements completely since water was not a simple substance but the product of two gases. it was lavoisier who hearing of the experiment gave cavendish's gas the name hydrogen ("water-producer") and added that hydrogen burned by combining with oxygen and that water was a hydrogen-oxygen combination.
