FAQ
Q: What is the formula used?
A: The tool applies m = (I * t * M) / (z * F) to find the theoretical maximum metallic mass loss over time, with F = 96485 C/mol.
Q: How does time unit affect calculation?
A: You enter time in hours; it is automatically converted to seconds for the Faraday constant.
Q: Can I get the result in kilograms?
A: Yes, toggle the unit switch to see the loss in kilograms (just divide grams by 1000).
Q: Is this calculation accurate for real systems?
A: It provides a theoretical upper bound; real-world losses are often lower due to incomplete charge transfer and other factors.
