A separatory funnel contains the two immiscible liquids water and hexane. Use the given densities to determine which layer is on top and which is on the bottom in the binary mixture.

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.
