Question

Consider the combustion reaction for octane (C,H,), which is a primary component of gasoline. 16CO,+ 18 H,O 2C,H+2502 How many moles of CO, are emitted into the atmosphere when 24.6 g C,H,, is burned? mol CO2 CO, emitted:

Answer 1

Balanced equation: 2C,H,(1)+ 250, (8) +1600, (g)+18H,0(1) Mass of the C,H, is 24.6g Molar mass of CH, is 114.238 mole mole Number of moles of C H = 24.6gx; 114.23g =0.215 mole 16moleco Number of moles of CO2 is produced = 0.215 mole CH18 * 2molec H18 = 1.72 mole co
