What is Atomic Mass?
Atomic Mass Calculator: Atomic mass, also known as atomic weight, is the mass of an atom expressed in atomic mass units (amu). It is approximately equal to the sum of the number of protons and neutrons in the nucleus of an atom. Electrons have negligible mass and are usually not included in this calculation.
How Does the Atomic Mass Calculator Work?
The Atomic Mass Calculator simplifies the process of determining the mass of an element or a molecule. By entering the element's symbol and the number of atoms, or by providing the molecular formula, the calculator computes the total atomic or molecular mass.
Steps to Calculate Atomic Mass Manually
- Identify the element or compound for which you need to calculate the atomic mass.
- Check the periodic table for the atomic masses of each element.
- For compounds, multiply the atomic mass of each element by the number of atoms in the formula.
- Add up all the values to get the total molecular mass.
Why Use an Atomic Mass Calculator?
The Atomic Mass Calculator is a time-saving tool for students, teachers, and professionals in chemistry. It eliminates manual errors and provides accurate results quickly, which is especially helpful in complex molecular calculations.
Example Calculation
Let’s calculate the molecular mass of water (H2O):
- Hydrogen (H): Atomic mass = 1 amu, Number of atoms = 2
- Oxygen (O): Atomic mass = 16 amu, Number of atoms = 1
Total molecular mass = (2 x 1) + (1 x 16) = 18 amu
