Mole Tables When setting up a reaction, organic chemists use a mole table to figure out the mass and volume of reagents needed based on the reaction stoichiometry. The mole table is a convenient way to organize all the information needed to determine the limiting reagent and theoretical yield, which are then used to calculate percent yield.
