Mole of Candy Lab
Stoichiometry
Purpose:
The purpose of this lab is to understand the quantity of a mole and use dimensional analysis to
convert representative particles <-> moles using m&m and skittle pieces.
Materials:
Digital Balance
6 (#1-#6) Bags of candy
1 Empty Ziploc bag
Calculator
Lab notebook
Pencil
 Use must use dimensional analysis to solve these problems.
 Always recalibrate and zero out the balance with the empty Ziploc bag before taking
the mass of any bag of candy.
 DO NOT OPEN THE ZIPLOC BAGS OR EAT THE CANDY!!!

M&M Mole Lab
Stoichiometry
Purpose:
The purpose of this lab is to understand the quantity of a mole and to make
conversions from grams to mole to representative particles using M&M’s.
Make the following conversions using dimensional analysis. Make sure you include
units in all calculations.
1. 1 dozen m&m’s =_______________#m&m’s=_______________grams (mass of bag #1)
2. Calculate the mass of 5 m&m’s using the conversions from step 1.
mass of 5 m&m’s = ________________
3. Measure the mass of bag #2 ___________________.
4. Calculate the number of m&m’s in bag #2.
Bag #2=______________________m&m’s
5. Calculate the number of dozens in bag #2 using the conversion in step 1.
Bag#2=______________________dozen
6. 1 dozen of skittles = _______________#skittles=__________________grams (mass of
bag #3).
7. Calculate the mass of 1500 skittles using the conversions from step #6.
Mass of 151=_________________________
