This 19 slide PowerPoint can be used to introduce dimensional analysis or conversion factors. It starts off with an example problem of calculating mass of a bushel of apples. This presentation to use on a smart board or projector/whiteboard. The answers do not come up but it gives you plenty of room to write the examples down. Great practice for a chemistry teacher who is moving toward teaching stoichiometry. Topics include: calculating molecular mass, formula mass, mole-mass calculations, and percent composition.
