1. What is Quantity of Charges Calculator?

Definition: This calculator determines the electric charge transferred through a circuit based on the mass of ions and the equivalent weight of the substance.

Purpose: It helps chemists and physicists calculate the amount of charge involved in electrochemical reactions.

2. How Does the Calculator Work?

The calculator uses Faraday's law formula:

Where:

• \( C_{tran} \) — Electric charge transferred (Coulombs)
• \( m_{ion} \) — Mass of ions (kilograms)
• \( E \) — Equivalent weight of substance (kilograms)
• 96485 — Faraday's constant (C/mol)

Explanation: The mass of ions is multiplied by Faraday's constant and divided by the equivalent weight to determine the total charge transferred.

3. Importance of Charge Calculation

Details: Accurate charge calculation is essential for understanding electrochemical processes, battery design, and electrolysis applications.

4. Using the Calculator

Tips: Enter the mass of ions in kilograms and the equivalent weight of the substance in kilograms. Both values must be greater than 0.

5. Frequently Asked Questions (FAQ)

Q1: What is Faraday's constant?
A: Faraday's constant (96485 C/mol) represents the electric charge carried by one mole of electrons.

Q2: How do I find the equivalent weight?
A: Equivalent weight is the molar mass divided by the number of electrons transferred in the reaction.

Q3: What units should I use?
A: Use kilograms for both mass and equivalent weight to get charge in Coulombs.

Q4: Can I use grams instead of kilograms?
A: Yes, but both mass and equivalent weight must be in the same units (either both kg or both g).

Q5: What practical applications does this have?
A: This calculation is used in electroplating, battery charging/discharging, and industrial electrolysis processes.
