If 33.7 ml of 0.210 M KOH is required to completely neutralize 27.0 ml of a HC2H3O2 solution, what is the molarity of the acetic acid solution?
mols KOH = M x L = ?
mols acetic acid = mols KOH (from the coefficients in the balanced equation.)
M acid = mols acid/L acid. You know mols and L, solve for M.
