How many moles of oxygen will react with 13.7 moles of ethane according to the following reaction? 2C2H6 +7O2—->4CO2 +6H2O

Answer 1

2C₂H₆ + 7O₂ ==> 4CO₂ + 6H₂O ... balanced equation

13.7.........?........

Using the coefficients of the balanced equation (stoichiometry) and dimensional analysis, we have....

13.7 mol C₂H₆ x 7 mol O₂ / 2 mol C₂H₆ = 48.0 mol O₂ needed
