The balanced chemical reaction is:

HCl + NaOH → NaCl + H2O

We are given the amount of sodium hydroxide to be used for the reaction. This will be the starting point of our calculations.

0.040 mol NaOH (1 mol HCl / 1 mol NaOH) = 0.040 mol of HCl

Therefore, the correct answer is the third option, 0.040 moles.

0.040 mol NaOH (1 mol HCl / 1 mol NaOH) = 0.040 mol of HCl

Therefore, the correct answer is the third option, 0.040 moles.
