I think the correct answer from the choices listed above is option B. <span>24 mL of Mg burn in 32 mL O2 to produce 56 mL of MgO </span>does not show the law of conservation of mass. Volumes cannot be added because there are volume effects when you add different substances. So, the reactants is not equal to the product.
To find the percentage yield you must take the actual yield and divide it by the theoretical yield and times it by 100. (Percent yield=Actual/Theoretical * 100)
For this example the calculated (Theoretical value) was 4.8 tones and the tones produced (Actual value) was 3.2 tones.
So 3.2/4.8 *100 = 66.6666666….
