Question

Gaseous ethane (CH3CH3) reacts with gaseous oxygen gas to produce gaseous carbon dioxide and gaseous water. What is the theoretical yield of water formed from the reaction of 27.4g of ethane and 47.9g of oxygen gas?

Answer 1

27.4 gm Ca Ho mol = 27.4 gm 30 gm /mol = 0.913 mol CHG. 47.9 qm O2 mol = 47.9 32 gr/mol - 1.497 mo la i combution Reaction 2 C₂H6 + 70 - 4 CO₂ + 6H₂O 0.913 mol 1.497 mol | 6:080.4565 1.1992 - 0.2138 limiting Reagent.
