1. What is Mass of Atom of Element Calculator?

Definition: This calculator determines the mass of a single atom of an element using Avogadro's number and the element's gram atomic mass.

Purpose: It helps chemists and physics students understand and calculate the extremely small mass of individual atoms.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( M_{atom} \) — Mass of 1 atom (kg)
• \( GAM \) — Gram Atomic Mass (g)
• \( [Avaga-no] \) — Avogadro's number (6.02214076 × 10²³)

Explanation: The gram atomic mass is divided by Avogadro's number to find the mass of a single atom, then converted to kilograms.

3. Importance of Atomic Mass Calculation

Details: Understanding atomic mass is fundamental in chemistry for stoichiometric calculations, material science, and nuclear physics.

4. Using the Calculator

Tips: Enter the gram atomic mass of the element (found on periodic tables). The result will be in kilograms (SI unit for mass).

5. Frequently Asked Questions (FAQ)

Q1: What is Avogadro's number?
A: It's the number of particles (atoms, molecules, etc.) in one mole of substance, approximately 6.022 × 10²³.

Q2: Where can I find gram atomic mass?
A: Periodic tables list atomic weights which are numerically equal to gram atomic masses.

Q3: Why is the result so small?
A: Atoms are extremely tiny, so their individual masses are correspondingly small (typically 10⁻²⁶ to 10⁻²⁵ kg).

Q4: Can I calculate for molecules?
A: Yes, use the molecular weight (sum of atomic weights) instead of gram atomic mass.

Q5: Is this exact for all isotopes?
A: No, this gives the average atomic mass accounting for natural isotope abundance.
