5. A 1.08 g sample of an unknown monoprotic acid is titrated with 36.50 mL of 0.215 M NaOH. Calculate the molar mass of the acid. Sketch the molecular structure of acetylsalicylic acid in aspirin and calculate its molar mass. Write the formula as C,H,O, 6. 7. A student dissolves a 0.726 g aspirin tablet in water and titrates the solution with 0.272 M NaOH. 12.05 mL of NaOH are required to reach the equivalence point. Calculate the per- centage of acetylsalicylic acid in the tablet.
