#### Answer:

#### Explanation:

I'll assume it reacts with *excess* oxygen, and forms only calcium oxide. The chemical equation for this reaction is

First let's calculate the number of moles of

Now, let's use the stoichiometrically equivalent values (the coefficients) in the chemical equation to calculate the number of moles of

Therefore,

By the way, I've never seen
