Question

You have 2.5 moles of a gas contained in a 4.2-L bulb at a temperature of 35°C. This bulb is connected to a 18.7-L sealed, initially evacuated bulb via a valve. Assume the temperature remains constant. (a) What should happen to the gas when you open the valve? Calculate any changes of conditions. The gas will flow from the 4.2 L bulb into the 18.7-L bulb. Eventually, the gas will be evenly dispersed throughout the two bulbs v At this point, there will be 2.5 moles of gas, the volume will be 14.5 XL, and the pressure will be 15.06 x atm.
