Assuming the molor mass of paraffin is 280 g/mol, calculate the # of mols of paraffin burned. Then calculate the heat of combustion of paraffin in kJ/mol I don't think I can help you with the information provided. We need an equation (although we can wing that one) but we also...

Yes. I wondered if confuded was a new word I should learn. I think the problem is a stoichiometry problem IF you know the heat of combustion. Do you know that? If so, then C3H8 + 5O2 ==> 3CO2 + 4H2O So it takes 44 g C3H8 to generate ??kJ (the heat of combustion generally ...

The temperature rises from 25.00 C to 29.00 C in a bomb calorimeter when 3.50 g of sucrose undergoes combustion in a bomb calorimeter. Calculate Erxn for the combustion of sucrose in kJ/mol sucrose. The heat capacity of the calorimeter is 4.90 kJ/C . The molar mass of ...

Is the molar enthalpy of combustion of pentane the same as the molar enthalpy of formation of pentane? No. The molar enthalpy for the combustion is for the reacton C5H10 + (15/2)O2 ==> 5CO2 + 5H2O The molar enthalpy for the formaton is 5C(graphite) + 5H2(g) ==> C5H10(l) ...
