A 21.70mL volume of 0.0940 M NaOH is required to reach the phenolphthalein endpoint in the titration of a 3.06g sample of vinegar.

a. calculate the number of moles of acetic acid in the vinegar sample.

b. calculate the mass of acetic acid in the vinegar sample. The molar mass of acetic acid is 60.05g/mol.

c. calculate the percent by mass acetic acid in the vinegar sample. Assume the density of the vinegar is 1.00 g/mL. Express the percent acetic acid in the vinegar to the correct number of significant figures.
