Balancing Chewing Gum

Purpose: We will practice using mass and the electronic balance.

Which type of gum had a greater loss of mass after chewing? Why?
Regular gum lost more mass because it has sugar.
What substance cause the loss of mass during the chewing?
The sugar.
Was there a difference in the texture between the two types of gum?
Sugar was harder than the regular gum because it has sugar in it.
Given that sugar has 4 calories per gram, how many calories would you estimate are in a stick of gum?
8 times 4 = 32 calories
How would you determine the mass of 10ml of milk? We would put it in a lightweight container than we would use the electronic balance to mass the milk. Than we would have to subtract the mass of the container!
