The molecular formula of propane is #C_3H_8#.Replacing 2 H-atom in its molecule by 2#NH_2# groups we get the molecular formula of diamino propane as #C_3H_6(NH_2)_2 equivC_3H_10N_2#

Now number if electrons in

#C->6,H->1,and N->7#

So total number of electrons in the molecule

#3xx6+10xx1+2xx7=42#
