When 4.00 g of propane is burned in excess oxygen, 0.2 grams of carbon dioxide is actually produced. Calculate the % yield.
I have no idea how to do this please show me how you get the answer

It's pretty low yield
C3H8 + 5O2 = 3CO2 + 4H2O
Convert 4 g of propane to moles
From the balanced equation, you make 3 moles of CO2 for every mole of propane.
To get the mass of CO2, multiply the moles of CO2 by its molar mass.
% yield = 0.2 g / theoretical yield from above. * 100
