Concept: Boyle's Law
From the Ideal Gas Law we get Boyle's Law. P1V1 = P2V2
Notice that V2 is the total volume after all the stopcocks are opened. V2 = 1 L + 1 L + 2 L = 4 L
Now we need to find the partial pressures of each gas separately.
Consider the three flasks in the diagram below. Assuming the connecting tubes have negligible volume, what is the partial pressure of each gas and the total pressure after all the stopcocks are opened?
