The apparatus...

Question

The apparatus consists of three temperature jacketed 1.000 L bulbs connected by stopcocks. Bulb A contains a mixture of $H_{2} O (g)$ , $C O_{2} (g)$ , and $N_{2} (g)$ at $25^{\circ} C$ and a total pressure of 564 mm Hg. Bulb B is empty and is held at a temperature of $- 70^{\circ} C$ . Bulb C is also empty and is held at a temperature of $- 190^{\circ} C$ . The stopcocks are closed, and the volume of the lines connecting the bulbs is zero. $C O_{2}$ sublimes at $- 78^{\circ} C$ , and $N_{2}$ boils at $- 196^{\circ} C$ .
How many moles of $C O_{2}$ are in the system?
