How much energy must be removed from a 125 g sample of benzene (C6H6) vapor at 425.0 K to make it a solid at 200.0 K? Use the following steps to get to your answer. You MUST show your work to receive any credit. The following physical data for benzene may be useful. The quiz will be due at the beginning of class on 2/17/16. ÎHvap = 33.9 kJ/mol ÎHfus = 9.8 kJ/mol Cliq = 1.73 J/g°C Cgas = c Csol = 1.51 J/g°C Tmelting = 279.0 K Tboiling = 353.0 K
1) Determine number of moles the sample contains.
