Chemistry homework

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

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?
