A36 gram sample of water has an initial temperature of 22 degrees celsius after the sample absorbs 1200joules of heat energy the final temperature of the sample is

Base on the question that states to calculate the final temperature of the sample if a 36 gram sample of water has an initial temperature of 22 degrees celcius after the sample absorbs 1200 joules of heat energy, base on that, the answer would be 30 degree celcius. I hope this would help 

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.
