Consider the three flasks in the diagram below. When the stopcocks are closed, the three flasks have the following volume and pressure values: He 1.00 L at 200. torr, Ne 1.00 L at 410 torr, Ar 2.00 L at 250 torr. 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?
