Stoichiometry Foldable Directions 2
DIRECTIONS:
Step 1: MOLE to MOLE Conversion
 Fold the sheet of paper in half “hot dog” style. Now fold the paper in half once then
another time, giving you four folded sections
 Open the paper up, and then fold the 2 outermost sections toward the middle. Giving you
four sections facing you
 On the top left and top right sections make a small box in each section and write MOLE
 On the uppermost left section write “Moles of Given”. At the bottom of the section, in
parenthesis, write from the problem
 On the uppermost right section write “# of Moles of Unknown”. At the bottom of this
section in parenthesis, write coefficient from balanced equation
 On the bottom right section write “# of Moles of Given”. At the bottom of this section, in
parenthesis, write coefficient from balanced equation
 The bottom left section should be left BLANK
 This is the set up (or T-chart) for a mole to mole conversion
Step 2: MASS to MASS Conversion
 Open up the foldable to the inside, there are eight blank sections here
 On the top outermost left and right sections make a small box in each section and write
MASS. *These sections can also apply to representative particles to representative
particles or liters to liters
 On the uppermost left section write “Mass of given”. At the bottom of the section, in
parenthesis, write from the problem
 In the next upper section, the 2nd section, write “1 Mole of the Given”
 In the third upper section, write “# of Moles of Unknown”. At the bottom of this section
in parenthesis, write coefficient from balanced equation
 In the last upper section, all the way to the right, write “Molar Mass of unknown”. At the
bottom of the section, in parenthesis, write find on the periodic table
 The bottom left section should be left BLANK
 In the next bottom section, the 2nd section, write “Molar Mass of the Given”. At the
bottom of the section, in parenthesis, write find on the periodic table
 In the next bottom section, the 3rdsection, write “# of Moles of Given”. At the bottom of
this section, in parenthesis, write coefficient from balanced equation
 In the last bottom section, all the way to the right, write “1 Mole of Unknown”.
 This is the set up (or T-chart) for a Mass to Mass (or gram to gram) conversion.
*This type of problem is considered to be a 3 step conversion; because you are
using 3 different conversion factors. *A MOLE to MASS or MASS to MOLE
Conversion are considered to be 2 step problems because you use 2 conversions (molar
mass of given to mole of given and then mole ratio between known and unknown)
