A sample of oxygen gas has a volume of 150 mL when its pressure is 114 kPa. If the pressure is increased to standard pressure and the temperature remains constant, what will the new gas volume be?

Hey how did you manage to type such a big lab report

The problem here is that according to aufbau principle before 3d orbital 4s subshell comes.after filling 3p orbital with electrons you have 4 electrons left, you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with the same spin.
