Question

A 2.839-g sample of C2H4O was burned in a bomb calorimeter whose total heat capacity is 16.77 kJ/°C. The temperature of the calorimeter increases from 22.62°C to 26.87°C. What is the heat of combustion per mole of C2H4O?

Answer 1

q = 16,770 x delta T =? J

delta H/g = ?J/2.839
delta H/mol = delta H/g x molar mass

Answer 2

8.90 x 103 kJ/mol
