Asked by Bob
A .2688-g sample of a monoprotic acid neutralizes 16.4 mL of .08133 M kOH solution, calculate the molar mass of the solution?
First of all how can I calculate the molar mass?

I think the question is "last of all how can I calculate the molar mass?).
HA + KOH ==> KA + H2O
mols KOH = M x L = ?
mols HA = mols KOH since the ratio of the coefficients is 1:1.
Then mols HA = grams HA/molar mass HA. You have grams and mols, solve for molar mass.
