Question

need to solve part c

1. The apparatus shown below consists of three 1.00L bulbs connected by stopcocks and held at the temperatures shown. Bulb A contains a mixture of H2O, CO2, and N2 at 25°C and a total pressure of 564 mmHg. Bulbs B and C are empty. CO2 sublimes at -78°C and N2 boils at -196°C 25 °C -70 -190 °C a. The stopcock between A and B is opened. The pressure in A and B is now 219 mmlHg. What do bulbs A and B contain? (5 points) b. How many moles of H20 are in the system(5 points) c. Both stopcocks are opened. The pressure throughout the system is 33.5mmHg. What do bulbs A, B and C contain? (10 points) d. How many moles of N2 are in the system? (10 points) c. How many moles of CO2 are in the system? (10 points)

Explanation / Answer

CO2 sublimes at -780C and boiling point of N2 is -1960C so when all the stopcocks are open

B flask contains CO2 and N2, C flask contains only N2 and A contains water (H2O)
