Question

What is the final temperature in the bomb calorimeter if 1.785 g of benzoic acid (HC7H5O2) is combusted in a calorimeter with a heat capacity of 5.02 Kj/degrees C and initial temperature of 24.62 degrees B? The heat of combustion of benzoic acid is -26.42 Kj/g
I know that q=m x c x delta T

Answer 1

\(q=m*C*(T_f-T_i) \rightarrow T_f=\dfrac{q}{m*C}+T_i \)

Answer 2

q=-26.42 Kj/g
C=5.02 Kj/
m=1.785 g
Ti=24.62 °C
find Tf
