What Is the Percent Yield of SO2 from CS2 in This Reaction?

[Koskesh]

Homework Statement

What is the % yield of 0.112g S02 obtained from the combination of 0.0781g of CS2 according to the reaction CS2 + 3O2 --> CO2 + 2SO2

Homework Equations

I believe it's Actual yield / Theoretical yield x 100% ?

The Attempt at a Solution

Not sure would 0.112g go under the AY? I don't now even know where to start.

Looks like you know what you're doing. The equation's right and the actual yield is .112 g SO₂. How do you find the theoretical yield?
