If you put 3 grams of N2 gas and 2 grams of O2 gas into a 2.5L tank and seal it at 283.15K what is the pressure inside the tank? Solve this problem by doing it this way.

1 calculate the moles of N2 and O2 gas by using the periodic table.
2 Use the ideal gas law to calculate the pressure inside the tank from Nitrogen

3 Use the ideal gas law to calculate the pressure inside the tank from Oxygen.

4. Add the two pressures together to get the total pressure.
