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
