For their first trial, a student pipettes 5.00 mL of a vinegar solution into an Erlenmeyer flask. The student titrates the vinegar with standardized NaOH with a molarity of 0.437 M. The volume of titrant used was recorded in the table above. Calculate the molarity of the vinegar solution for this trial. Enter a number without units.

2. For his second experiment, Samuel uses vinegar instead of acetic acid powder. He sets up three experimental trials with different reaction conditions. He records all his data in the table below for the three trials. Trial Mass of Baking Soda (g) Temperature (°C) Volume of Vinegar (mL) Reaction time to completion (s) 1 10.0 25.0 60.0 41 10.0 40.0 60.0 23 3 10.0 55.0 60.0 12 c) Why does Samuel achieve a reaction in each of these trials, but he saw no reaction when he mixed powders of pure acetic acid and pure baking soda?
