1. How many mL of 3 M NaOH are required to make a 1 L solution of 0.1 M NaOH?

 

2. A student placed 10.00 mL of a hydrochloric acid solution in an Erlenmeyer flask. She then added 16.6 mL DI water and 2 drops 0.2% phenolphthalein solution. During the titration, a faint, pale pink color was observed when 18.50 mL of 0.262 M barium hydroxide had been added.

Calculate the concentration (in M) of the original hydrochloric acid solution.
