The formula used to calculate the Percent Change in Mass (PM) is:
\[ PM = \left( \frac{Mf - Mi}{Mi} \right) \times 100 \]
Where:
The Percent Change in Mass is a measure of the change in mass expressed as a percentage of the initial mass. It is commonly used in various scientific fields to quantify changes in mass over time or under different conditions.
Let's assume the initial mass is 50 kg and the final mass is 75 kg.
Using the formula:
\[ PM = \left( \frac{75 - 50}{50} \right) \times 100 = \left( \frac{25}{50} \right) \times 100 = 50 \% \]
Therefore, the Percent Change in Mass is 50%.
