Volume of NaOH titrated if the initial buret reading was 19.2 mL and the final buret reading was 35.48 mL

In order to find the volume of NaOH titrated, you need to subtract the initial buret reading from the final buret reading.

Volume of NaOH titrated = Final buret reading - Initial buret reading

Volume of NaOH titrated = 35.48 mL - 19.2 mL

Volume of NaOH titrated = 16.28 mL
