A solvent has a freezing point of 10°C. What is the most likely freezing point if 5 grams of Salt is mixed with the solvent? (AKS 5e) Question 5 options:

15°C

20°C

5°C

10°C

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
