A0.1276 g sample of an unknown monoprotic acid was dissolved in 25.0 ml of water and titrated with 0.0633 m naoh solution. the volume of base required to bring the solution to the equivalence point was 18.4 ml. (a) calculate the molar mass of the acid. (b) after 10.0 ml of base had been added during the titration, the ph was determined to be 5.87. what is the ka of the unknown acid?

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).
