A flask is filled with vapor by boiling a volatile unknown liquid in the flask. As it boils away, the vapor of the unknown pushes the air out of the flask through a tiny pinhole opening and eventually the flask is filled with an atmosphere composed exclusively of the unknown. When the flask is allowed to cool, the vapor condenses and air again refills the flask.

Q: Is the error in volume measurement or the error in mass measurement greater in this experiment?
