Answer:

The reaction takes place is

 2 (C2H6) + 7 (O2) → 4(CO2) + 6(H2O) 

According to the equation,

60g ethane requires 7x32= 224g oxygen

here ethane is in excess.oxygen will be consumed completely.

hence

2.9 g O2 will consume 60×2.9/224=0.776g of C2H6

now,

2 moles of C2H6 produces 4 moles of CO2!

60g ethane produces 4x44 g CO2

hence amount of CO2 produced =4×44×0.776/60=2.27g
