A student performs a titration experiment to determine the molar mass of an unknown solid monoprotic acid, \(\text{HA}\). A \(0.420\text{ g}\) sample of \(\text{HA}\) is dissolved in \(50.0\text{ mL}\) of distilled water and titrated with standardized \(0.100\text{ M }\text{NaOH(aq)}\). Before the titration begins, an air bubble is trapped in the buret tip below the stopcock. During the titration, the air bubble is completely expelled as the solution is delivered, and the titration is stopped precisely at the equivalence point. Which of the following best explains how the presence and loss of the air bubble affects the recorded volume of \(\text{NaOH(aq)}\) delivered and the resulting calculated molar mass of \(\text{HA}\)?
