You are provided with 6.05 g S O 2 to react with 2.23 g O 2. Indicate your theoretical yield.

Write and balance the equation

2SO2 + O2 - > 2SO3

4SO2 + O2 - > 2S2O5

I assume is the first reaction

Calculate the theoretical yield for each of the reactants and the lowest yield will be the theoretical yield of the reaction produced by the limiting regent. Calculate the molecular mass of SO2, SO3, and O2 from the atomic mass of the elements in the periodic table.

6.05 g SO2 x 80.1g SO3 / 64.1 g SO2 = 7.56 g SO3

2.23g O2 x 2 * 80.1 g SO3 / 32gO2 = 11.16 g SO3
