Homework Answers
The percent acetic acid is: 0.80 mol/L x {60 g CH3COOH/mol} x {1 L/1000 mL} x {1 mLvinegar/1 g vinegar} x 100% = 4.8 % acetic acid.

During the calculations for titration of vinegar experiment, you determined the molar mass of KHP by using the mass of K, H, and P instead of using KHC8H4O4. How would this change your results? Explain. We had to find the mass of KHP, moles of KHP, moles of NaOh, and moles of acetic acid, molarity of vinegar titrated, mass of acetic acid titrated in grams, and w/v % of acetic acid in vinegar

I am supposed to find the individual and average weight percents of acetic acid in vinegar and the relative percent error between my average results and the manufacturers listed value. Data 6ml vinegar @ 5% acetic acid 3.585g vinegar 42.2ml of NaOH @ 0.100M I'm not sure how to do this at all and want to understand. I know we need to use the molarity equation somewhere. If anyone can list the steps I need to take to answer the...

Calculate the moles of acetic acid, molarity of the vinegar solution, and mass %. of acetic acid in the vinegar using the average of three good trials used to titrate 5.00 mL of the vinegar. You may assume that the density of your vinegar sample is 1.01 g mL^-1. Drain off unused NaOH solution into a clean container and place it into a designated container. Wash the buret two times with regular tap water, then rinse with deionized water, and...

• Material from the Acid-Base Titration Experiment. If you were to overtitrate without realizing it, would the following results come out too high, too low or unchanged? Be able to explain your answer. concentration of acetic acid in vinegar • mass percent of acetic acid in vinegar? o What is the purpose of adding deionized water to the vinegar in the Erlenmeyer flask? Does it affect the endpoint? Explain why or why not.
