Calculate the resulting pressure if 4.50 liters of nitrogen at 35 degrees Celsius and 790 torr and 3.7 liters of oxygen at 15 degrees Celsius and 750 torr are pumped into a 1.00 liters container at 25 degrees celsius. Assume ideal gas behavior.

Use PV = nRT and solve for n N2.
Use PV = nRT and solve for n O2
Add n = mols to find total mols.
Then use PV = nRT and solve for P in the new container at the new conditions.
