What mass of carbon dioxide is produced if you burn 80.0 grams of C5H12 with 240.0 grams of O2

Question

Using the equation C5H12 +8O2 ---> 5Co2 + 6H20

Answer 1

Start by writing the correctly balanced equation:

C₅H₁₂ + 8O₂ ==> 5CO₂ + 6H₂O ... balanced equation

Next, find the limiting reagent:

80 g C5H12 x 1 mol C5H12 / 72 g x 5 mol CO2 / mol C5H12 x 44 g CO2/mol CO2 = 244 g CO2

240.0 g O2 x 1 mol O2 / 32 g x 5 mol CO2 / 8 mol O2 x 44 g CO2 / mol CO2 = 206 g CO2
