molarity The molarity of NaOH was used in the titration of the weight of the unknown acid, using phenolphthalein as an indicator. By using the concentration this NaOH solution, the weight of the unknown acid that was titrated, and the volume of NaOH that was used to titrate it, we can determine the weight of the unknown acid. Trial 1 Trial 2 Trial 3 Final- initial volume 21.7-1.33= 20.37 24.7-4.05= 20.65 45.06-23.09 = 21.97 HCl calculations Trial 1 Trial 2 Trial 3 22.37/10= 2.237 20.65/10=2…
