What is the percent yield for the reaction of 6.92 g of K and 4.28 g of O2 if 7.36 g of KO2 is recovered in the laboratory?

First you need to find the theoretical yield for the reaction:
2Na + O2 ---> Na2O2
(1) find the theoretical yield of 3.74 g of Na, i.e. if all of the Na is reacted
3.74 g Na *(1 mol Na/22.99 g Na)*(1 mol Na2O2 formed/2 mol Na reacted)*(77.98 g Na2O2/1 mol Na2O2) = 6.34 g Na2O2
(2) % yield = (actual yield / theoretical yield)*(100%)
% yield = (5.34 g / 6.34 g) *(100%) = 84.2% yield

When 320g octane C8H18 is burned in oxygen 392g of water is recovered what is the percent yield of the experiment?
the percent yield be the actual yield (392) divided by the theoretical yield (i calculated 450). 392/450 equals .87 multiply by 100 and the percent yield is 87%.
