The molar heat of fusion of ethanol is 4,60 kJ mol and its molar heat of Ethanol has a normal of liquid ethanol is 2.45 J/g. C and that,of gaseous ethanol is 1.43 Jg ion is 38.56 kJ/mol. 0.114 5 and a normal boling port of 78 4 °C The specific heat capacity Number kJ be Check Answer NextE

Explanation / Answer

heat required(q) = n*DHfus + mliquid*Sliquid*DT1 + n*DHvap + mgas*Sgas*DT2

                 = (20.7/32)*4.6*10^3 + 20.7*2.45*(78.4-(-114.5))+ (20.7/32)*38.56*10^3 + 20.7*1.43*(162.6-78.4)

                 = 40.2 kj
