1011+AP+Vinegar+Titration

The AP chemistry students collected the following data when titrating 5.00 mL samples of acetic acid with 1.00 M NaOH.


 * Group Members || Trial || Initial Vol Reading || Final Volume Reading ||
 * Maaike & Joanna || 1 || 4.00 || 9.00 ||
 * Maaike & Joanna || 2 || 9.00 || 13.55 ||
 * Maaike & Joanna || 3 || 13.55 || 17.25 ||
 * David || 1 || 3.10 || 6.75 ||
 * David || 2 || 6.75 || 10.70 ||
 * Iikka and Shaun || 1 || 5.00 || 8.73 ||
 * Iikka and Shaun || 2 || 8.73 || 12.23 ||

From these data, the following results were calculated.


 * Group Members || Trial || Volume NaOH added || mol OH- added || mol HAc present || [HAc] ||
 * Maaike & Joanna || 1 || 5.00 || 0.00500 || 0.00500 || 1.00 ||
