Three glass bulbs, joined by closed stopcocks, have the following volumes and initial pressures of the specified gases. Bulb A: 100. mL of CO(g) at 190. torr

Bulb B: 200. mL of H2S(g) at 1.00 atm

Bulb C: 500. mL of Kr(g) at 75.994 kPa

After both stopcocks are opened and the gases allowed to diffuse throughout, what will be the final total pressure?

(The ambient temperature is constant.)

Ptotal = 0.750 atm

What is the partial pressure of H2S(g)?

PH2S =

What is the mole fraction of Kr(g)?

ΧKr =
