Consider two flasks connected by a stopcock. One flask has a volume of 500.0 mL and contains N2(g) at a pressure of 700.0 Torr. The other flask has a volume of 400.0 mL and contains O2(g) at a pressure of 950.0 Torr. If the stopcock is opened so that the two gases mix completely - calculate the partial pressure of N2(g) and O2(g) and the total pressure of the resultant mixture. I am getting 698 Torr for N2(g) and 953 Torr for O2(g), but the answer is 388.9 Torr for N2(g) and 422.2 Torr for O2.
