How to Use the Calculator

  1. Enter the molecular weight of the substance in g/mol in the "Molecular Weight" field.
  2. Enter the mass of the substance in grams in the "Mass" field.
  3. Click the "Calculate" button to compute the number of particles.
  4. The result will be displayed in the "Number of Particles" field in scientific notation.
  5. Click the "Reset" button to clear all input fields and start over.

Working Principle

The AvogadrosNumberCalculator uses Avogadro's number (6.022 × 10²³ particles/mol) to calculate the number of particles in a given amount of substance. The formula used is:

Number of Particles = (Mass / Molecular Weight) × Avogadro's Number

This calculation is essential in chemistry for converting between the mass of a substance and the number of particles (atoms, molecules, ions, etc.) it contains.

Example

For example, to calculate the number of water molecules in 18 grams of water (H₂O), you would:

  1. Enter 18.0 in the "Molecular Weight" field (the molecular weight of water is approximately 18.0 g/mol).
  2. Enter 18.0 in the "Mass" field.
  3. Click "Calculate".
  4. The result would be 6.022 × 10²³ molecules of water.
