C + O2 ==> CO2
Convert 10.120 g CO2 to mols.
Convert mols CO2 to mols O2.
Convert mols O2 to grams O2.
Post your work if you get stuck.
(As it turns out, the 2.760 g C was apparently pure C so the same process could have been used with the 2.760 g C but the problem doesn't say pure C so the SURE way is to do it the way I outlined.)
