Answer to Question #136642 in General Chemistry for Audra

Question

A 0.18 mol sample of a substance is combusted in a bomb calorimeter with a heat capacity of 5.11 kJ/°C. The temperature inside the calorimeter increases by 25.7 °C. What is the energy per mol (kJ/mol) for the combustion reaction? 

Answer 1

0.18 mol of substance

5.11kj/^OC heat capacity

Calorimeter 25⁰C

Therefore:

( 5.11kj/⁰C) / ((0.18M)(25))

(5.11/25.18) J / ⁰C

=0.203J/⁰C
