To find the number of moles of NaOH used in the titration, we need to use the equation:

moles = concentration x volume

Given that the concentration of NaOH solution is 0.1000 M and the volume used in the titration is 7.08 mL, we can calculate the number of moles as follows:

moles = 0.1000 M x 0.00708 L

First, we need to convert the volume from milliliters (mL) to liters (L) by dividing by 1000:

0.00708 L = 7.08 x 10^-3 L

Now, we can calculate the number of moles:

moles = 0.1000 M x 7.08 x 10^-3 L

moles = 7.08 x 10^-4 mol

Therefore, 7.08 x 10^-4 moles of NaOH were used in the titration.
