The stopcock between a and b is opened. the pressure in a, Ask an Expert

Academics

An apparatus consists of three 1.00L bulbs connected by stopcocks and held at where Bulb A=25 celcius, Bulb B= -70 celcius, Bulb C= -190 celcius. Bulb A contains a gas mixture of H20 (g), CO2 (g), and N2 (g) at 25 celcius and a total pressure of 564 mmHg. Bulbs B and C are empty. Co2 sublimes at -78 celcius and N2 boils at -196 celcius.

A. The stopcock between A and B is opened. The pressure in A and B is now 219mmHg. How many moles of H20 are in the system?

What I know: Bulb A contains CO2 (g), N2 (g). Bulb B contains CO2 (g), N2 (g), H20 (s). Somehow use PV=nRT

B. Both stopcocks are opened. The pressure throughout the system is 33.5 mmHg. How many moles of N2 are in the system? How many moles of CO2 are in the system?

What I Know: Bulb A contains N2 (g), Bulb B contains N2 (g) and H20 (s). Bulb C contains N2 (g) and CO2 (s).
