Consider an apparatus that consists of two flasks joined together by a valve. One flask consists of 10 L of nitrogen gas at 790 torr, whereas the other flask contains 16 L of helium gas at 740 torr. The temperature remains constant at 26?C. The valve is opened and the gases are allowed to mix. What is the total pressure of the gas mixture?
1. 759.2 torr
2. 765.0 torr
3. 1,530 torr
4. 790 torr
5. 740 torr
