Moles of NaOH titrated when 16.28 mL of a 0.12M solution of dilute NaOH

To find the moles of NaOH titrated, we need to use the formula:

moles = concentration × volume

Given that the concentration is 0.12 M and the volume is 16.28 mL (or 0.01628 L), we can plug in the values:

moles = 0.12 M × 0.01628 L

moles = 0.0019536 moles

Therefore, 0.0019536 moles of NaOH were titrated.
