Below are hypothetical data from a titration experiment. Part A focuses on determining the molarity of a sodium hydroxide solution. Part B uses the sodium hydroxide solution to determine the molarity, and ultimately the mass percent, of acetic acid in an unknown vinegar sample. Vinegar is an aqueous solution containing 4 to 6% by mass acetic acid. Please use the data provided below to perform the calculations and answer the questions in this assignment. Part A: A 0.883 M standard...
