    Answer:

    The reaction takes place is

     2 (C2H6) + 7 (O2) → 4(CO2) + 6(H2O) 

    According to the equation,

    60g ethane requires 7×32= 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 4×44 g CO2

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