Consider the arrangement of bulbs shown in the drawing. Each of the bulbs contains a volume of gas as shown. PN2 = 700. torr, PNe = 206 torr, and PH2 = 402 torr. What is the pressure of the system when all the stopcocks are opened, assuming that the temperature remains constant? (We can neglect the volume of the capillary tubing connecting the bulbs.)torr
