Three glass bulbs, joined by closed stopcocks, have the following volumes and initial pressures of the specified gases.
Bulb A: 250. mL of H2S(g) at 380. torr
Bulb B: 500. mL of He(g) at 0.250 atm
Bulb C: 1.25 L 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.)

What is the partial pressure of H2S(g)?

What is the mole fraction of Kr(g)?
