Moles & Molar Mass Calculator

Determine the mass of a substance using the formula m = n × M, where:

Ideal for students, chemists, and anyone involved in chemical reactions, this tool lets you quickly compute the mass of a compound or element by inputting the number of moles and its molar mass. Whether you’re balancing equations, preparing solutions, or studying stoichiometry, this calculator streamlines your work and saves you time.

How It Works

  • Moles (n): Represents the quantity of substance (1 mole = 6.022 × 10²³ particles)
  • Molar Mass (M): The mass of one mole of the substance (sum of atomic masses)
  • Mass Calculation: m = n × M

Example

For 2 moles of H₂O (M = 18.016 g/mol):

Mass = 2 × 18.016 = 36.032 grams
