A 100.0 g (m) pith (molecular influence 50.00 g/mol) requires 75.1 J (q) to enjoy 5 position C acception, (a) reckon the C and Cm values. (b) If we envelop the sum of the pith (i.e. 2m), reckon the C and Cm values. (c) Determine intensive or abundant properties coercion m, C, Cm, and q.

we insufficiency to reckon inequitable ebullition capacility Q=m*C*DetaT
c=Q/m*detaT
c=75.1/5*100
c=0.1502 J/ g C
If we reckon molar ebullition cleverness cm
cm=spcific ebullition cleverness*molecular influence of the subatanc
so from interrogation we recognize the molecular influence 50gm/mol
we already reckond inequitable ebullition cleverness c
cm=50*0.1502
cm=7.51j/mol/K
