If you are referring to the Erlenmeyer flask, a stopper would not change anything as the flask is just a vessel for the solution. However, the flask does get heated and you should never heat a closed flask.
Please review the chemical equation on page 40 of the lab manual in order to determine the mole ratio between acetylsalicylic acid and the tetraaquosalicylatroiron (III) ion created via the reaction of ASA and hydrated iron III ion.

what was the volume of HCI used
why is ethanol used in this experiment?
Hi! Ethanol is used to assist in dissolving the aspirin.
Would placing a stopper on the conical flask make any difference to validity or is it fine without it?

How do i calculate the no. of moles of acetyl salicylic acid? Which formula should i use for the collected data

By using the mole ratio between acetyl wali yo if acid and NaOH
