Question

Indicate whether each of the following experimental errors wouldresult in an incorrectly larger or smaller calculated molar volumefor CO2, or if it would have no appreciable effect on thecalculated molar volume. Assume the procedure described in thismodule was used. Briefly explain your answers.

The mass will be determined by weighing a flask filled with airand then reweighing the same flask filled with CO2 gas. The CO2 gaswill come from allowing a piece of solid CO2 to sublime in the saidflask.

A. Too much Dry Ice was added to the flask

B. After determing the mass of the flask, stopper, and air, thestudent used a stopper with less mass than the original stopperwhen he weighed the CO2-filled flask.
