Balloon X is filled with the carbon monoxide. Balloon Y is filled to the same volume with carbon dioxide. The balloons are left for several days in a room at constant temperature. Which balloon would you expect to be smallest after this period of time?
The rate of effusion through the balloon walls is inversely proportional to the molar masses. In simpler terms, a lower molar mass means the gas escapes faster. Therefore, the CO (molar mass 28) will squeeze through the balloon pores faster than the CO2(molar mass 44).
