How this calculator works
Moles are n = m/M.
Formula
n=m/MAmount of substance from sample mass and molar mass.
Worked example
Verified example is a verified test case used by the calculation engine.
Assumptions and limitations
- Mass is non-negative.
- Molar mass must be positive.
- Use compatible mass units.
Methodology & sources
This calculator uses deterministic, versioned calculation logic. The formula and verified examples above are part of the calculation definition used by CalcuMint. Technical calculation version: 1.

Frequently asked questions
What is molar mass?
It is mass per mole of the substance.
Can molar mass be zero?
No, because the formula divides by molar mass.
