Answer #1

1)

The stopcock connecting a **3.15** L bulb
containing **carbon dioxide** gas at a pressure of
**9.69** atm, and a **4.15** L bulb
containing **xenon** gas at a pressure of
**2.59** atm, is opened and the gases are allowed to
mix. Assuming that the temperature remains constant, the final
pressure in the system is .... atm.

pressure of CO2 P1 = 9.69 atm

P2 = ??

volume v1 = 3.15 L

V2 = 3.15 + 4.15 = 7.3 L

P1 V1 = P2 V2

9.69 x 3.15 = P2 x 7.3

P2 = 4.18

pressure of CO2 = 4.18 atm

Pressure of xenon = 2.59 atm

volume = 4.15 L , V2 = 7.3 L

2.59 x 4.15 = P2 x 7.3

P2 = 1.47 atm

**final pressure in the system = 5.65 atm**
