Let’s Go On a Trip!
• Your Moletro tickets indicate your current
location and where you want to go
• For example – ticket #1 is used to go from
Moles (central station) to
atoms/molecule/particle (particleville)
• Also on your ticket is the conversion factor
(the relationship between one unit and
another)
Memorize the Conversion Factors!!!!!
• 1 mole = 6.02 X1023 particles
• 1 mole = molar mass in grams
• 1 mole = 22.4 L (volume)
• These are used in the 2nd column
or your T-chart
All Aboard the Moletro to???
Trip #1 - What is the volume of 3 moles of CH4?
(need moles  liters ticket)
3 moles CH4
22.4 Liters
1 mole
= 67.2 Liters CH4
#2 What is the number of moles of oxygen in an 85
Liters of oxygen? (need Liters  moles ticket)
85 L
1 mole
= 3.8 moles
22.4 L
#3 How many grams does 5 moles of 53I weigh?
(need moles  grams ticket)
5 moles 127 g
1 mole
= 635 g
#4 How many molecules are in 1.5 moles of
glucose? (need moles  molecules ticket)
1.5 moles 6.02 x1023 molecules
1 mole
= 9.03 x 1023
molecules
#5 How many moles is 88 g of CO2? (need g 
moles ticket) (molar mass of CO2 = 12 + 2 (16) = 44g)
88 g
1 mole
44 g
= 2 moles
#6 How many moles is 176 g of CO2? (need g 
moles ticket)
– First I need to calculate grams of CO2.
12 + 2( 16) = 44 g
176 g
1 mole
44 g
= 4 moles
One Mole can equal 3 different things
1. 6.02 X 1023 atoms or molecules
2. The mass of any element or molecule in
grams
3. 22.4 Liters of any gas
•
Since the mole can equal any one of these,
it can also serve as a bridge to convert from
one to another of them.
