The hint tells you how to work the problem.
mols NaOH = M x L = ?
mols acid = mols NaOH since it is 1:1 ratio.
Then M acid = mols acid/L acid = ?
Calculate the Molarity of the unknown acid if 25.0 mL of the acid reacts with 17.50 mL of 0.14 M NaOH solution. Assume that NaOH and acid react in 1:! ratio. Show your work.
(Hint: Find the moles of NaOH from the given molarity and volume. mols of NaOH = mols of acid. Knowing mols and volume of acid, calculate molarity of the acid)
