This contains 2 free response questions written in they style of AP. These questions revolves around percent composition, molar mass, and empirical formula calculations students would learn in a PreAP Chemistry course. Each successive part (parts a-e here for both) of any FRQ potentially builds on itself and emphasizes a deeper understanding of the topic.
The first two documents are two different versions of these questions - one to print as a full page and one to print as half sheets. The third document contains scoring guidelines that are also written in the style of AP.
I use these questions for homework, but they could be used classwork or a quiz.
