Question

                                        How many molecules of carbon dioxide are produced when 1 x 1024 molecules of octane are combusted (use your previously                                         balanced chemical equation for the combustion of octane #1).                                     

                                        What mass of carbon dioxide is produced when 1 x 1024 molecules of octane are combusted (use your previously balanced                                         chemical equation for the combustion of octane #1).                                     

                                        How many carbon dioxide molecules are produced for every gram of octane combusted (use your previously balanced chemical                                         equation for the combustion of octane #1)?

                                        Suppose you are going on a picnic and you are bringing sandwiches. You find all the ingredients that you have in your                                         kitchen and your goal is to make as many sandwiches as you can.                                     

                                
                                You find:                             

                                26 slices of bread
                            

                                14 pieces of meat
                            

                                3 tomatoes
                                16 leaves of lettuce
                            

                                15 pieces of cheese                             

                                You want to make your sandwiches with 2 slices of bread, 1 piece of meat, 1 pieces of cheese, 2 slices of tomato (each tomato can                                 be sliced into 9 slices) and 1 leaf of lettuce.                             

                                How many sandwiches can you make?                             

Explanation / Answer

1)

6.023*10^23------------------------------------1mole of octane

1024 molecule of octane----------------------------------?

=1024/6.023*10^23=170.01*10^-23moles

1 mole of ocatne gives--------------------------------------------------------8 *6.023*10^23co2 molecules

170.01*10^-23 moles------------------------------------------------------?

=170.01*10^-23*8*6.023*10^23

=1360.11*6.023

2168.94 co2molecules are produced

2) one co2 molecule--------------------------44 gram

2168.94CO2 MOLECULES------------------/

=2168.94*44

=95433.47 GRAMS OF CO2

3)114 grams of octane gives------------------------8 *6.023*10^23 CO2 MOLECULES

      1 gram of octane-----------------------------?

=8/114

=4.22*10^22 co2 molecules
