Question

6- Explain the need to calculate percent change in mass vs. simply change in mass (weight gain or weight loss) over time.

Answer 1

Answer:

what are you saying i dont no

Answer 2

The need to calculate percent change mass over the simple change in mass is based on the accuracy of percent change mass.

• Percent change in mass shows the proportion of a substance's mass that has changed over time.
• For example, during weathering of rocks, the rocks undergo several changes like change of mass. If one-fourth of the mass is weathered,  then the mass of the rock will change by 25%.
• We calculate the percent change in mass over the simple change in mass because the accuracy provided by the percent change in mass is more reliable than the simple change in mass.
• Calculating the change in mass using their differences can be done when the initial masses are similar.
