The absorption of water/saliva from your mouth to the gum would likely be a valid explanation for an increase in mass. Hope this helps!

The absorption of water/saliva from your mouth to the gum would likely be a valid explanation for an increase in mass.

What assumption is made about the reason for the change in mass after chewing the gum?

Because if something weighs 1g and changes by 1g, that's really important. If it ways 1kg and changes by 1g, that's much less important. As such, percentage mass is always used to show how big the change was, relative to the existing mass

One way to calculate mass: Mass = volume × density. Weight is the measure of the gravitational force acting on a mass. The SI unit of mass is "kilogram". The SI unit of weight is Newton (N).
