The mass of a product found by a scientist in the lab is also called
What is the Actual Yield
It's units are grams per mole
What is Molar Mass
You would use this conversion factor if you were solving a stoichiometry equation with two substances

Its the reactant that is left over after the reaction
What is the Excess Reagent (or reactant)
It's the same number whether it's unit is atoms or molecules.
What are Representative Particles
Dimensional analysis uses this to convert from a known Unit to a wanted unit.
