40 POINTS!! Will Mark Brainliest if all work is shown as well as correct answer

The following reaction can be used to convert carbon dioxide to oxygen gas.

4 KO₂ (s) + 2 CO₂(g) → 2 K₂CO₃(s) + 3 O₂(g)

The theoretical yield for the reaction is 0.296 g O₂. Given that the reaction has a percent yield of 83.4%, what is the mass in g of oxygen gas that is actually produced?
