Question

Calculate the total heat to convert 0.821 moles of gaseous ethanol t

Answer 1

Boiling point at 1 atm 78.5°C
cgas 1.43 J/g·°C
cliquid 2.45 J/g·°C
ΔH°vap 40.5 kJ/mol

q=mcΔT.

So...
.349(1.43)(674-298)=187.65
+
.349(2.45)(674-298)=321.498
= 509.1488

that was an easy question and im only 11
