A gas occupies 195 cm3 at 43 degrees * C . Find its volume at 75 degrees * C

D.na is the answer hope this

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.

Iam not going to tell you
