Question

I keep getting the third part of this quastion wrong, can someone explain why?

Consider the data table
Compound melting point (c) Alt fuc (K)/ wal) Baling pt Attrap (K)/as)
HBC
-86.96
2.406
- 67.0
19.27
Calculate AS fus & ASvap for HBC.
ASfus AH fus
Tm
-8460273
A Svap = Altvap =
213 +-41
2.406x10² 12.93 J
186.04
19.27 X10²
204
93.54 J
As 12.93+ 93.54 = 106.47
Determine the entropy change when 8.50 mal HBr freezes
at atmospheric pressure, 27.8 X 12.13 = -100.75
101.40 X
(7.50 mil) (12.93) = 109.90
