Measurement of Vm of CO2 in a Flask: The Importance of Accuracy

What is the significance of stoppering the flask before measuring the volume of CO2 in determining the experimental Vm?

A. Higher

B. Lower

C. Stay the same

Answer:

If the flask is not stoppered, the experimental determined Vm of CO2 would be lower.

Stoppering the flask before measuring the volume of CO2 is crucial in obtaining accurate results for the experimental Vm. When the flask is not stoppered, the CO2 gas can escape, leading to an underestimation of the volume of the gas. This results in a lower Vm value compared to the actual value.

By ensuring that the flask is properly stoppered, you trap the CO2 gas inside, allowing for a more precise measurement of the volume. This leads to a higher Vm measurement, reflecting the true volume of CO2 present in the flask.
