A cylinder of volume 50 L contains oxygen gas at a pressure of 2 atm. If nitrogen gas of volume 25 L and at pressure 1 atm is added to the oxygen cylinder, the new pressure is Group of answer choices 2 atm. 3 atm. 2.5 atm. 3.5 atm. 4 atm.
Homework Answers
According to ideal gas equation -
PV = nRT
P is pressure, V is Vollume, T is temperature, R gas constant, n is number of moles
So for nitrogen gas pressure in 50 L will be 0.5 atm
When both will combined in oxygen cyllender than according to daltons law -
Total pressure (P) = 2 + 0.5
P = 2.5 atm
