Molality= moles NaCl/ Kg H2O

250 g (1 Kg/ 1000 grams)= 0.250 Kg

Molality= 0.611 moles/ 0.250 Kg= 2.44 molal

What is the heat of combustion of ethane, c2h6, in kilojoules per mole of ethane? Enthalpy of formation values can be found in t
Andre45 [30]

The balanced combustion reaction for one mole of ethane will be

C2H6 + 3.5 O2  ---> 2CO2(g) + 3H2O (l)

Enthalpy of reaction of combustion = ∑ΔHf (products)- ∑ΔHf (reactant)

ΔHf = enthalpy of formation

The enthalpy of formation of oxygen = 0 as it is an element in its native state

ΔHf C2H6 = -83.820 kJ / mole

ΔHf H2O = -285.830 kJ / mole

ΔHf CO2 = -393.509 kJ / mole

ΔHrxn = [2 X ΔHf CO2 + 3 X ΔHf H2O] - [ΔHf C2H6]

ΔHrxn = [2 X (-393.509) + 3 (-285.830)] - [-83.820]

ΔHrxn = -1560.688 kJ / mole
