A 1.213g sample of an unknown weak monoprotic acid was titrated to the endpoint with 27.25mL of a 0.3016M NaOH Calculate:
-the number of moles of base reacted.
-the number of moles of acid originally present.
-the molar mass of the acid.

  • chemistry - ,

    mols base = M x L = ?
    For a monoprotic acid mols acid = mols base
    mols acid = grams acid/molar mass. You know mols and grams, solve for molar mass.
