Explanation / Answer

part B)

volume of acetic acid = 33.7 mL

volume of solution = 245 mL

volume % =( volume of solute / volume of solution ) x 100

                = (33.7 / 245 ) x 100

volume % = 13.8 %

part C)

mass / volume % = mass of NaCl / volume of solution ) x 100

                           = 15 / 45.5 ) x 100

                          = 33.0 %
