When a 2.00 L flask containing 0.340 atm of gas A is joined with a 4.00 L flask containing 0.820 atm of gas B, and the stopcock between the flasks is opened, and the gases are allowed to mix thoroughly at constant temperature, what is the resulting total pressure of gases in the now-joined flasks? (assume no reaction between the gases and that the gases behave ideally)
A. 1.09 atm
B. 0.660 atm
C. 0.223 atm
D. 1.16 atm
