A bomb calorimeter can be used to measure the enthalpy of reaction for combustions, such as the combustion of diborane represented by the following balanced equation: B2​H6​(g)+3O2​(g)➔B2​O3​(s)+3H2​O(g) ΔHcombustion for this process is –1958 kJ/mol. Assume that 0.411 g of diborane is combusted in a calorimeter whose heat capacity (Ccalorimeter) is 7.854 kJ/°C at 22.61°C. What is the final temperature of the calorimeter? The answer is not 18.922°C

Question

A bomb calorimeter can be used to measure the enthalpy of reaction for combustions, such as the combustion of diborane represented by the following balanced equation:

B2​H6​(g)+3O2​(g)➔B2​O3​(s)+3H2​O(g)

ΔHcombustion for this process is –1958 kJ/mol.

Assume that 0.411 g of diborane is combusted in a calorimeter whose heat capacity (Ccalorimeter) is 7.854 kJ/°C at 22.61°C. What is the final temperature of the calorimeter?

The answer is not 18.922°C
