This is a flipped classroom activity intended for use in a first semester general chemistry course. Students are expected to have prior knowledge in determining the molar mass of compounds, how to carry out mole/gram conversions, and how to write balanced chemical reactions. The activity includes:
1) pre-lecture learning videos that guide students through carrying out basic stoichiometric calculations, determining the limiting reactant, and determining the percent yield of a reaction;
2) a pre-lecture interactive tutorial that helps students learn the concept of limiting reactant;
3) pre-lecture quiz questions; and
4) an in-class activity that requires students to apply their knowledge of stoichiometry and limiting reactant in the real-world application of converting coal to liquid fuel.

Students are expected to complete the following learning objectives:
a) using mole-gram conversions and mole-mole conversions to carry out stoichiometric calculations for balanced chemical reactions;
b) gaining appreciation for how stoichiometric calculations are used in real-world chemical reactions.
Prior to completing this activity, students will be expected to have learned how to use molar masses of elements and compounds to carry out mole-gram conversions, how to balance chemical reactions, and how to use balanced chemical reactions to carry out mole-mole conversions.
