How much heat is needed to raise the temperature of 50g of a substance by 15c when the specific heat is 0.92?

The  heat  needed  to  raise  the  temperature   of  50g  of  substance  by    15 c   is  calculated as   follows

Heat  =   mc delta  T

m= mass   (50g)
c=  specific  heat  capacity  (0.92)
delta T=  change  in  temperature(  15 c)

heat  is  therefore=   50   x  0.92  x  15  =  690   

Nb:  my   answer  has  no  units  since   the   given   specific  heat  capacity  has   no  units

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.
