Initial NaOH Volume (mL) Final NaOH Volume (mL) Total volume of NaOH used (mL)

Trial 1 9.10 2.60 6.50

Trial 2 9.20 2.80 6.40

Trial 3 9.40 2.00 7.40

Average Volume of NaOH Used (mL):  6.77

Data Table 2.Concentration of CH₃COOH in Vinegar

Average volume of NaOH used (mL) - 6.77

Concentration CH₃COOH in vinegar (mol/L) - ?

% CH₃COOH in vinegar  - ?

1. Using the data provided above, determine the average concentration (moles per liter) of acetic acid (CH3COOH) present and determine % concentration (mass percent) of acetic acid (CH3COOH), when 5 mL of vinegar were used for each trial. Please show all work and explanations.

Here is a equation provided for the moles (no sure if this is correct or how to use): CH3COOH = L NaOH x mol NaOH/L x 1 mol CH3COOH/ 1 mol NaOH x 1/0.005 L
