Grams to Moles Calculator

Calcolatore da grammi a moli (e viceversa)

Formula: n = m / M · dove n = moli, m = massa, M = massa molare (g/mol).

A) Grammi ➜ Moli
B) Moli ➜ Grammi
Suggerimenti: ottieni la massa molare dalla formula chimica (es. H₂O ≈ 18,015 g/mol). 1 kg = 1000 g.

The Grams ⇄ Moles Converter by UtileApp is an intuitive chemical calculator that allows you to instantly convert between mass and moles — perfect for chemistry students, teachers, and laboratory professionals.

Simply enter the mass (in g or kg) and the molar mass (g/mol) of your compound to get the number of moles immediately.
You can also perform the reverse calculation to find the mass from a known number of moles.

Main features

🔹 Grams → Moles: n=mMn = frac{m}{M}n=Mm​

🔹 Moles → Grams: m=n×Mm = n times Mm=n×M

🔹 Supports both grams and kilograms for flexible input.
🔹 Scientific notation output for clear, precise results.
🔹 Clean, user-friendly interface ideal for educational or lab use.

Use and benefits

Perfect for:

  • Chemistry and biology students learning molecular calculations;
  • Teachers and laboratory staff working with substances and reagents;
  • Anyone needing to understand the relationship between mass, moles, and molar mass.

Example

🧪 18 g of H₂O with M = 18.015 g/mol → 1 mole
🧪 0.5 mol of NaCl with M = 58.44 g/mol → 29.22 g

A must-have chemistry calculator for performing fast, accurate stoichiometric conversions between mass and moles.
