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.
D
.
The unchewed gum had a greater mass than the chewed gum because it was measured with the wrapper.
A. The chewed gum had a lower mass than the unchewed gum because a substance in the gum dissolved in the student's saliva.
This conclusion is most likely correct as the mass of the chewed gum is lower than the unchewed gum, indicating that something from the gum was lost during the chewing process, likely due to dissolution in saliva.
