#=0.52molCO_2#

Explanation:

  1. Write and balance the equation.
    #2C_4H_10+13O_2->8CO_2+10H_2O#
  2. Given the mass of #O_2#, convert this value to mole through molar conversion using the molar mass of #O_2# as conversion factor; i.e.,
    #=27cancel(gO_2)xx(1molO_2)/(32cancel(gO_2))#
    #=0.84375molO_2~~0.84molO_2#
  3. With reference to the balanced equation for the mole ratio of #O_2# and #CO_2#, find the mole value of #CO_2# through molar conversion.
    #=0.84cancel(molO_2)xx(8molCO_2)/(13cancel(molO_2))#
    #=0.52molCO_2#
