A 0.298 g sample of an unknown monoprotic acid is titrated with 0.300 M KOH to the equivalence point. It requires 15.8 mL of KOH to reach this point. Elemental analysis is also performed, showing that the acid contains 1.6% H, 22.2% N, and 76.2% O. Use this information to determine the molecular formula and the molar mass of the unknown acid. molecular formula of unknown acid: HNO molar mass of unknown acid: Draw the Lewis structure of the unknown acid in which the H atom(s) are bonded to O atom(s). g/mol
