44a) A student decided to determine the molecular mass of a solid monoprotic acid, HA, by titrating a solution of a known mass of the acid. The following recordings were made: Mass of bottle/ g +/- 0.001 g: 1.737 Mass of bottle + acid HA / g +/- 0.001 g: 2.412 Calculate the mass of the acid and determined its absolute and percentage uncertainty 44b) This known mass of acid, HA, was then dissolved in distilled water to form a 100.0 cm^3 solution in a volumetric flask. A 25.0 cm^3 sample of this solution reacted with 12.1 cm^3 of a 0.100 mol dm^-3 NaOH solution. Calculate the molar mass of the acid.
