Pure ammonia (NH3) is contained in a glass bulb from which a capillary tube leads to the atmosphere. The bulb has a volume of 1.0x104 m³, and the capillary tube has a 1 mm inside diameter and a length of 10 cm. The system is at a temperature of 20°C and a pressure of 1 atm. Determine the time for the mole fraction of NH3 in the bulb to decrease to 0.5 if the concentration of NH3 in the atmosphere is negligible.
