The table below shows the masses of a piece of gum and its wrapper before and after the gum was chewed by a student.
MASS OF GUM
Objects Placed on Scale Mass (g)
Unchewed gum with wrapper 9.0
Chewed gum with wrapper 8.6
Wrapper 2.0
Using the table, which conclusion is most likely correct?
A.
The chewed gum had a lower mass than the unchewed gum because a substance in the gum dissolved in the student's saliva.
B.
The mass of the gum remained constant throughout the experiment because the gum did not contain any soluble substances.
C.
The chewed gum had a greater mass than the unchewed gum because saliva dissolved into the gum as it was chewed.
