Mastication
Lab
Purpose:
Determine the percent composition of sugar in different kinds of chewing gum
Procedure:
1.
Obtain a wrapped up piece of gum. Record
mass of gum and the wrapper on data
table.
2.
Carefully
unwrap the gum and place it in your mouth.
Chew out the sugar in the gum. (do not throw
out the wrapper!)
3.
After you have swallowed most of the sugar in the gum.
Record
mass of ABC (already been chewed) gum and
the wrapper on data table.
4.
Record
mass of gum on data table.

chemical equation for sugar is: C12H22O11)
Do the following questions ONLY if you chewed a sugar gum!
2. How many moles of sugar were in you gum?3.
How
many molecules of sugar were in your gum?
Do the following questions ONLY if you chewed a sugar free gum!
2. The Molar Mass of NutraSweet is 294.3 g/mole. If you had sugar free gum, how many moles of NutraSweet did you have?3. If you had sugar free gum, how many molecules of NutraSweet did you have?
