Question

Using the following equation for the combustion of octane, calculate the amount of grams of carbon dioxide formed from 100.0 g of octane. The molar mass of octane is 114.33 g /mole .The molar mass of carbon dioxide is 44.0095 g/mole.
2 C8H18 +25 O2 ---->16 CO2 +18 H20
/\H 11018 kJ

Answer 1

Part from the Question

Answer 2

molar mass of octane is 114.33 g /mole
molar mass of carbon dioxide is 44.0095 g/mole.

100.0 g of octane x 1 mol octane/ 114.33 g /mole ="A" moles of Octane in 100 g

"A" moles of Octane in 100 g x 16 mole of CO2 / 2 mole octane= "B" moles of CO2

"B" moles of CO2 x 44 g CO2/ 1 mol CO2 = "C" grams of CO2
