Hi there, I am having a problem with this question, any help would be great.
Use the following balanced chemical equation to calculate the mass of carbon dioxide produced from the burning of 5.50 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

1. Write the equation and balance it.
2. Convert 5.5 kg to moles of jet fuel. # moles = grams/molar mass.
3. Using the coefficients in the balanced equation, convert moles of the jet fuel to moles of the product (in this case CO2).
4. Now convert moles CO2 to grams.
grams = moles x molar mass.
Post your work if you get stuck.
