Question- Your Flasks A and B are connected by a stopcock. Initially flask A contains 1000.0 mL of O2 at 50 kPa pressure, while flask B contains750.0 mL N2 at 100 kPa pressure, both at 25 ºC. The stopcock is opened and the gases mix. What is the mole fraction of O2 in the final mixture?
If possible just a brief explanation how you got the answer?
