Preguntas frecuentes

What is molar mass?

Molar mass is the mass of one mole of a substance, expressed in grams per mole (g/mol). It equals the atomic or molecular weight from the periodic table.

Can I use this for molecules?

Yes, use the molecular mass (sum of atomic masses) for compounds. For elements, use the atomic mass.

What if I have mass in kilograms?

Convert kilograms to grams first (1 kg = 1000 g) before using the calculator.

Fórmulas

Las matemáticas detrás de esta calculadora, escritas para que puedas verificar el resultado.

Moles from mass

n = m / M

The number of moles (n) equals the mass (m) divided by the molar mass (M).

Example:

Input: m = 36.03 g, M = 18.015 g/mol

Calculation: 36.03 / 18.015

Result: 2.000 mol

Stoichiometry

Convert given masses to moles to balance chemical equations and find reactant or product amounts.

Example: Calculate moles of water from 100 g of water.

Solution preparation

Determine the amount of solute needed to make a solution of a specific molarity.

Example: How many moles of NaCl are in 58.44 g?

Lab experiments

Quickly convert measured masses to moles for quantitative analysis.

Example: Convert 12 g of carbon to moles.

Consejos y errores comunes

Tips

  • Use the most accurate molar mass from the periodic table for precise results.
  • Always include units in your calculations to avoid errors.
  • For compounds, sum the atomic masses of all atoms in the formula.
  • Remember that moles are a count of particles, not a mass.

Common Mistakes to Avoid

  • Using atomic mass in amu instead of g/mol.
  • Forgetting to convert mass to grams if given in kilograms.
  • Confusing molar mass with molecular weight without units.

Supuestos y limitaciones

  • Use the stated inputs and units.
  • Results are estimates for planning and education.
  • Check measurements and source data before making an important decision.
