Assuming that the bath contains 250.0 g of water and that the calorimeter itself absorbs a negligible amount of heat, calculate combustion energies (ΔE) for benzene in both kilojoules per gram and kilojoules per mole.

    kJ/mol

Explanation:

Given and known facts

Mass of Benzene grams

Mass of water grams

Standard heat capacity of water J/g∙°C

Change in temperature ΔT °C

Heat

Heat released by benzine is - 7.82 kJ

Now, we know that

grams of benzene release  kJ heat

So, g benzine releases

kJ/g

mol C6H6

Heat released

    kJ/mol
