Why is mass change measured in percentages?

Answer 1

It doesn't have to be, but that's the most convenient way.

If you do an experiment in your lab, and you discover something so amazing

that you want to tell everybody else about it, you want to make it as clear

to them as you can.

You started out with a sample that had 0.000034 grams of mass, and when

you were finished, the mass was 0.0000452 grams. What's the best way to

tell other people about your amazing results ?

-- Mass changed from to 0.000034 grams to 0.0000452 grams.

-- Mass changed from 34 micrograms to 45.2 micrograms.

-- Mass increased by 0.0000112 grams .

-- Mass increased 32.94 percent.

The last one gets the point across best. The amount you started with or

finished with doesn't matter to anybody. The really amazing part is that

it increased by almost 33% .

Answer 2

Measuring mass change in percentages allows for easy comparison between different samples or experiments regardless of their initial mass. It provides a standardized way to assess the magnitude of change relative to the initial amount, making it particularly useful for analyzing data and drawing conclusions from experiments.
