Greetings !!! And welcome to the board!!! Oxidation!!! Who-hoo!!!
Ahem ..
You've been given a mass of reactant, and you need a mass of product. You will have to convert one to the other. You will need a conversion equation, and you have one, the balanced chemical equation. It has units, it just doesn't include the symbols. Can you figure out what to convert, and where.
P.S. give the sub button up above a try when you next need to make subscripts.
