1. What is Percentage Change in Mass?

Percentage change in mass measures the relative difference between an initial mass and a final mass, expressed as a percentage. It is commonly used in scientific experiments, chemistry, physics, and material science to quantify mass variations.

2. How Does the Calculator Work?

The calculator uses the percentage change formula:

\[ \% Change = \frac{(New\ Mass - Old\ Mass)}{Old\ Mass} \times 100 \]

Where:

\( New\ Mass \) — Final mass measurement (g)
\( Old\ Mass \) — Initial mass measurement (g)

Explanation: The formula calculates the relative change in mass as a percentage of the original mass. Positive values indicate mass gain, negative values indicate mass loss.

3. Importance of Mass Change Calculation

Details: Calculating percentage change in mass is essential for monitoring chemical reactions, material degradation, biological processes, and quality control in manufacturing. It helps quantify efficiency, loss, or gain in various scientific and industrial applications.

4. Using the Calculator

Tips: Enter both mass values in grams. New Mass and Old Mass must be positive numbers, with Old Mass greater than zero. The calculator will compute the percentage change automatically.

5. Frequently Asked Questions (FAQ)

Q1: What does a positive percentage change indicate?
A: A positive percentage change indicates an increase in mass, meaning the new mass is greater than the old mass.

Q2: What does a negative percentage change indicate?
A: A negative percentage change indicates a decrease in mass, meaning the new mass is less than the old mass.

Q3: Can the percentage change be greater than 100%?
A: Yes, if the new mass is more than double the old mass, the percentage change will exceed 100%.

Q4: What units should I use for mass measurements?
A: The calculator uses grams (g), but the formula works with any consistent mass unit as long as both values use the same unit.

Q5: Why is Old Mass required to be greater than zero?
A: Division by zero is mathematically undefined, so Old Mass must be positive to calculate a meaningful percentage change.
