The combustion of toluene has a δerxn of −3.91 × 103kj/mol. when 1.60 g of toluene (c7h8) undergoes combustion in a bomb calorimeter, the temperature rises from 23.20 ∘c to 37.44 ∘c. find the heat capacity of the bomb calorimeter.

How much heat is released upon converting one mole of steam (18.0 g) from 100.0 ∘c to water at 25.0 ∘c? show work and constants, trying to figure out how it works. only given the heat capacity for steam and water so try to only use that
