Bulb A contains a mixture of H20(g), CO2 (g), and N2 (g) at 25° C and a total pressure of 560 mm Hg. Bulb B is empty and is held at a temperature of -70° C. Bulb C is also empty and is held at a temperature of -190° C. The stopcocks are closed, and the volume of the lines connecting the bulbs is zero. CO2 sublimes at -78° C, and N2 boils at -196 C (Figure 1) Figure 1 of 1 Part B How Exp 25 °C 70 °C 190 °C TH

Explanation / Answer

now the pressure will equally distribute in the 3 vessels.

therefore P = 560/3 mm and V = 1.710L

Part B:

moles of H2O = PV/RT = [(560/(3*760))*1.710 ]/(0.082*(25+273)) = 0.017 moles

Part E:

moles of CO2 = PV/RT = [(560/(3*760))*1.710 ]/(0.082*(-70+273)) = 0.0252moles

Part D:

moles of N2 = PV/RT = [(560/(3*760))*1.710 ]/(0.082*(-190+273)) = 0.061 moles
