Solving <strong>Stoichiometry</strong> Problems • So solving stoichiometry problems involves converting between these starting units to moles, and then from moles back to the units required at the end (mole map stuff.) • The typical sequence looks like this: • Amount known mol known mol unknown amount unknown • Each arrow represents a calculation.
Solving <strong>Stoichiometry</strong> Problems • Remember the screws, nuts and washers? • This is exactly the same kind of problem. • Grams of screws/mass of 1 screw = # screws. • # screws x 1 = # of nuts • # nuts x mass of 1 nut = g of nuts OR • # screws x 2 = # of washers • # washers x mass or 1 washer = g of washers.
