What is the percent yield of the reaction below when 544.5 g so2 and 160.0g o2 produce 382.0 g so3? 2so2+o2+2so3

Explanation:

We have the masses of two reactants, so this is a limiting reactant problem.  

We will need a balanced equation with masses and molar masses of the compounds involved. Gather all the information in one place

Mᵣ:      64.06     32.00     80.06

          2SO₂  +    O₂   ⟶  2SO₃

m/g:   544.5     160.0

1. Theoretical yield

(a) Calculate the moles of each reactant  

(b) Identify the limiting reactant  

Calculate the moles of SO₃ we can obtain from each reactant.  

From SO₂:

The molar ratio of SO₂ to SO₃ is 2:2

From O₂ :

The molar ratio of SO₂:O₂ is 2 mol O₂:1 mol O₂.

The limiting reactant is SO₂ because it gives the smaller amount of SO₃.

(c) Calculate the theoretical yield of SO₃.

2. Calculate the percent yield of SO₃
