Density to Moles Converter

Convert between density, mass, and molar mass to find moles of a substance

Input Parameters

Calculation Results

Calculation Formula

Moles = (Density × Volume) / Molar Mass

Where:
Moles = Amount of substance in moles
Density = Mass per unit volume (g/mL or g/cm³)
Volume = Space occupied by the substance (mL or cm³)
Molar Mass = Mass of one mole of the substance (g/mol)

Understanding the Formula

The calculator uses the formula:
Moles = (Density × Volume) / Molar Mass

This formula allows you to calculate the number of moles when you know the density and volume of a substance, as well as its molar mass. It's particularly useful in chemistry for converting between mass, volume, and amount of substance.

Example

If you have 500 mL of water with a density of 1.0 g/mL, and you know water's molar mass is approximately 18.015 g/mol, you can calculate:
Moles = (1.0 g/mL × 500 mL) / 18.015 g/mol = 27.735 moles

Applications

This calculator is useful in various chemistry applications including:

  • Preparing solutions of known concentration
  • Stoichiometric calculations in chemical reactions
  • Determining the amount of substance in a given volume
  • Calculating molar masses when other properties are known
