Percent Change in Mass Formula
The following formula is used to calculate the Percent Change in Mass.
PM = (Mf-Mi)/Mi*100
- Where PM is the Percent Change in Mass (%)
- Mi is the initial mass (kg)
- Mf is the final mass (kg)
To calculate the percentage change in mass, divide the change in mass by the initial mass, then multiply by 100.
How to Calculate Percent Change in Mass?
The following example problems outline how to calculate Percent Change in Mass.
Example Problem #1:
- First, determine the initial mass (kg).
- The initial mass (kg) is given as: 30.
- Next, determine the final mass (kg).
- The final mass (kg) is provided as: 50.
- Finally, calculate the Percent Change in Mass using the equation above:
%M = (Mf-Mi)/Mi*100
The values given above are inserted into the equation below and the solution is calculated:
%M = (50-30)/30*100 = 66.67 (%)
Example Problem #2:
For this problem, the variables needed are provided below:
initial mass (kg) = 60
final mass (kg) = 80
This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer.
%M = (Mf-Mi)/Mi*100 = ?
