Gaseous ethane will react with gaseous oxygen to produce gaseous carbon dioxide

Question

Gaseous ethane will react with gaseous oxygen to produce gaseous carbon dioxide and gaseous water . Suppose 29. g of ethane is mixed with 152. g of oxygen. Calculate the maximum mass of carbon dioxide that could be produced by the chemical reaction.
Round your answer to significant digits. Gaseous ethane (CH3CH3) will react with gaseous oxygen (O2) to produce gaseous carbon dioxide (CO2) and gaseous water (H2O) . Suppose 29. g of ethane is mixed with 152. g of oxygen. Calculate the maximum mass of carbon dioxide that could be produced by the chemical reaction.

Explanation / Answer

Your chemical equation should look like:

2 C2H6 + 7 O2 => 4 CO2 + 6 H2O

Solving for CO2 with each reactant will give:

29 g C2H6 x (1 mol C2H6/30.08 g C2H6) x (4 mol CO2/2 mol C2H6) x (44.01 g CO2/1 mol CO2) = 84.86 g CO2

152 g O2 x (1 mol O2/32.00 g O2) x (4 mol CO2/7 mol O2) x (44.01 g CO2/1 mol CO2) = 119.45 g CO2
