4. A chemist wants to determine the concentration of an acidic solution. They start by placing 25.0 mL of the acid in a flask. Then, they titrate it with 7.5 mL of 0.12 M NaOH. a. How many moles of NaOH were added to the acid? b. Assuming the acid and base react in a 1:1 ratio, how many moles of acid are in the flask? c. What is the molarity of the unknown acid?
