Question

PLEASE HELP Consider the combustion for octane (C8H18), which is a primary component of gasoline.

2 C8H18 + 25 O2 -> 16 CO2 + 18 H2O

HOW MANY MOLES OF CO2 are emitted into the atmosphere when 26.6 g C8H18 is burned?

CO2 emitted: (blank) mol CO2

Answer 1

Answer: 1.86 moles of CO2

Step-by-step explanation:

26.6 g C8H18 * (1 mole C8H18/ 114.26 g C8h18) * (16 mol CO2/ 2 mol C8H18) = 1.86 moles of CO2.

114.26 is the molar mass of C8H18: 8(12.01) + 18(1.01) = 114.26
