## Expert Answer

Step 1

The volume of NaOH consumed is subtracting final volume from initial volume.

V = 27.80 mL – 0.02 mL

= 27.78 mL

Step 2

The relation between millilitres (mL) and liters (L) is written in equation(2).

1 mL = 0.001 L

Convert 27.78 mL into liters by using the above relation.
