Moles of NaOH titrated when 20.98 mL of a 0.12M solution of dilute NaOH

Answer 1

To determine the moles of NaOH titrated, we need to use the equation:

Moles = Concentration x Volume

Given:
Concentration of NaOH solution = 0.12 M
Volume of NaOH solution = 20.98 mL

Before we calculate the moles, we need to convert mL to L:
20.98 mL = 20.98 / 1000 L = 0.02098 L

Now we can calculate the moles of NaOH titrated:
Moles = 0.12 M x 0.02098 L
Moles = 0.0025176 mol

So, the moles of NaOH titrated is approximately 0.0025176 moles.
