A sample of hydrogen gas (3.2 l) at 3.5 atm and 25 °c was combined with 5.2 l of nitrogen gas at 7.3 atm and 25 °C at constant temperature in a 15.0 l flask. Assuming the initial pressure in the flask was 0.00 atm and the temperature upon mixing was 25 °., What is the total pressure (atm) in the flask?

Can you me with this i really appreciate it
