# Chemistry Word Problem

The Apparatus shown below consists of 3 temperature-jacketed 1.000 L bulbs connected by stopcocks. Bulb A contains a mixture of H2O(g), CO2(g), and N2(g) at 25 degrees C and a total pressure of 564 mmHg. Bulb B is empty and is held at a temperature of -70 degrees C. Bulb C is also empty and is held at a temperature of -196 degrees C. You may neglect the volume of the lines connecting the Bulbs.

A) The Stopcock between A and B is opened,and the system is allowed to come to equilibrium. The pressure in A and B is now 219 mmHg. What do bulbs A and B each contain?

B) How many moles of H2O are in the system?

C) Both stopcocks are opened, and the system is again allowed to come to equilibrium. The pressure throughout the system is 33.5 mmHg. What do bulbs A, B, and C each contain?

D) How many moles of N2 are in the system?

E) How many moles of CO2 are in the system?
