Sophia Keller has been contacted by Foodlink to determine that the mass percent of acetic acid in their newest product, Vinagre deLite ,meets, but, does not exceed the industry standard of 5%acetic acid my mass.A 25mL portion of the diluted solution required 22.62 mL ofthe standardized NaOH to reach phenolphthalein end point.
a) How many moles of acetic acid are present in the titrated sample?
b) What is the molarity of the diluted solution?
c) How many moles of acetic acid are present in the original sample?
d) What is the molarity of the original undiluted sample?
e) Based on the number of moles of acetic acid present in theoriginal 25mL of vinegar analyzed, what mass of acetic acid is present?
f) What is the mass percent of acetic acid in Vinagre de Litebased on this 25mL sample? Assume the density of vinegar is1g/mol?
