I dropped chemistry after GCSE, so someone else may be better placed to answer this, but...

Mass = Mr x Moles where Mass = 11, Mr = 12 + 16 + 16 = 44.

Hence, Moles = 11/44 = 0.25 moles of CO2.

Thus, we have 0.25 x 1 = 0.25 moles of carbon and 0.25 x 2 = 0.50 moles of oxygen.

Hopefully that helps (and hopefully I'm correct).
