Data from a similar experiment is provided so that you can complete the lab calculations. Trial Trial 2 Trial 3 Mass of vinegar 19.27 g 19.57 g 19.62 g Initial buret reading 5.1 mL 43.8 mL $2.4 ml Final buret reading 43.8 ml. 81.3 ml. 90.1 ml A. Volume of NaOH used Lab Report for Lab 10: 1. Fill out row A in the table above - the volume of NaOH used in each trial. This is calculated by considering the final buret reading and the initial buret reading for each trial. 2. Answer the ALL lab report questions on page 81 and 82 (attached at end of handout). You must show ALL your work for full credit on the lab. To calculate the mass of acetic acid, (CH,COOH) that reacted in each trial: Set up a stoichiometry calculation as outlined below. For the first step in the calculation you will need to use the 0.40 M NaOH solution as a conversion factor. ml NaOH solution used in trial -> moles of NaOH -> moles CH,COOH -> g CH2COOH (acetic acid) To calculate the mass percent acetic acid in the vinegar in each trial: of acute and from the previous cau s ) Use % acetic acid x 100% After watching the youtube video link you should be able to consider possible sources of error to complete the last question in the lab report.
