free4spirit Posted May 15, 2011 Share Posted May 15, 2011 (edited) Hi all Just wondering if anyone out there can help me with one of my questions for my uni assignment? Use the following balanced chemical equation to calculate the mass of carbon dioxide produced from the burning of 3.73 kg of jet fuel which can be represented by the molecule C12H26. You should quote your answer to 3 significant figures in units of kg. The relative atomic masses (RAMs) needed to do this calculation are as follows; RAM (carbon) = 12.0; RAM (oxygen) = 16.0; and RAM (hydrogen) = 1.01. 2 C12H26 + 37 O2 = 24 CO2 + 26 H2O If anyone can please give me any advice or point me in the right direction, it would be greatly appreciated As i dont even know where to start! Thanks, Ax Edited May 15, 2011 by free4spirit Link to comment Share on other sites More sharing options...
Fuzzwood Posted May 15, 2011 Share Posted May 15, 2011 How many moles does 3.73 kg of jet fuel convert to? According to the reaction equation, 1 mole of jet fuel burns to 24/2 moles of carbon dioxide. How many grams of carbon dioxide would that be?

mississippichem Posted May 15, 2011 Share Posted May 15, 2011 [math] \frac {grams}{\frac {grams}{mole}} = moles [/math] Link to comment Share on other sites More sharing options...
