For each trial, calculate the mass of citric acid present in the fruit juice sample.

Next, calculate the mg of citric acid present per mL of juice.

Finally, average the mg of H3C6H5O7 / mL juice from each titration trial.

Trial 1:

Vol. of Juice(Citric acid) = 20 mL

Molarity of NaOH = 0.097 M

Final Buret reading: 18.2 mL

Initial: 25 mL

Trial 2:

Vol. of Juice(Citric acid) = 20 mL

Molarity of NaOH = 0.097 M

Final Buret reading: 11.078 mL

Initial: 25 mL

Trial 3:

Vol. of Juice(Citric acid) = 20 mL

Molarity of NaOH = 0.097 M

Final Buret reading: 9.18 mL

Initial: 25 mL
