Answer:

Balanced Eqn

2C2H6+7O2=4CO2+6H2O

By the Balanced eqn

60g ethane requires 7x32= 224g oxygen

here ethane is in excess.oxygen will be fully consumed

hence

300g oxygen will consume 60⋅300224=80.36g ethane

leaving (270-80.36)= 189.64 g ethane.

By the Balanced eqn

60g ethane produces 4x44 g CO2

hence amount of CO2 produced =4⋅44⋅80.3660=235.72g

and its no. of moles will be 235.7244 =5.36 where 44 is the molar mass of Carbon dioxide

Hope its help you
