What is the mathematical equation for Boyle’s law that you would use if: you had to solve for a new volume when given 2 pressure values and an old volume value.

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.

Ithink that the answer is b
