Indicate whether each of the following experimental errors would result in an incorrectly larger or smaller calculated molar volume for CO2, or if it would have no appreciable effect on the calcu-lated molar volume. Assume the procedure described in this module was used. Briefly explain your answers. (a) Too much dry ice was added to the flask. (b) After determining the mass of the flask, stopper, and air, the student used a stopper with less mass than the original stopper when he weighed the CO2-filled flask.
