While 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, as well as the stopcock between the flasks is opened, as well as the gases are allowed to mix thoroughly at constant temperature, Explain what is the resulting total pressure of gases in the now-joined flasks? Presume no reaction between the gases and that the gases behave ideally
