Question

Sulfur (3.26 g) is burned in a constant volume calorimeter with excess O2(g). The temperature increases from 21.25°C to 28.22°C. The bomb has a heat capacity of 923 J/K, and the calorimeter contains 815 g of water. Calculate ΔU per mole of SO2 formed, for the following reaction.

S8(s)+ 8 O2(g) 8 SO2(g)
