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!!! 1 dozen= 12 pieces M&M’s 1. Bag #1=_____________grams=_______________dozen=_______________pieces a. Measure the mass of bag #1. b. Count the number of m&m’s in bag #1. 2. Bag #2=_______________grams=_____________dozen=_________________pieces a. Measure the mass of bag#2. b. Use the conversion factor from step 1 to calculate the number of dozens. c. Use the conversion factor from step 1 to calculate the number of m&m’s . 3. Bag#3=________________grams=________________dozen=______________pieces a. Use the conversion factor from step 1 to calculate the number of dozens. b. Use the conversion factor from step 1 to calculate the number of m&m’s. Skittles 4. Bag#4=_______________grams=__________dozen=_____________pieces a. Measure the mass of bag #4. b. Count the number of pieces in bag#4 5. Bag#5=_______________grams=______________dozen=_____________pieces a. Measure the mass of bag #5. b. Use the conversion factor in step 4 to calculate the number of dozens. c. Use the conversion factor step 4 to calculate the number of skittle pieces. 6. Bag#6=______________grams=___________dozen=____________pieces a. Measure the mass of bag#6 b.
