Answer to Question #169317 in General Chemistry for Michael C Shimko

Question

Gaseous ethane CH3CH3 will react with gaseous oxygen O2 to produce gaseous carbon dioxide CO2 and gaseous water H2O. Suppose 0.601 g of ethane is mixed with 1.7 g of oxygen. Calculate the maximum mass of carbon dioxide that could be produced by the chemical reaction. Round your answer to 2 significant digits.

Answer 1

2CH₃CH₃ + 7O₂ ----> 4CO₂ + 6H₂O

Moles of ethane = 0.601/30

= 0.020 mol

Moles of O2 = 1.7/32

= 0.053 mol

O₂ is limiting reagent.

Mass of CO₂ produced = 4×44×1.7/7×32

= 1.3 g

Mass of carbondioxide = [1.3] g
