Mole Calculator
Convert between mass, moles, particles, and gas volume
Formula: n = m / M
Where n is moles, m is mass in grams, and M is molar mass in g/mol. Avogadro's constant = 6.022 × 1023 particles/mol.

⚠️ Gas volume calculations assume Standard Temperature and Pressure (STP defined as 0 °C and 1 atm, where 1 mole of an ideal gas occupies 22.414 Liters). Modern IUPAC STP uses 1 bar pressure ($22.711\text{ L/mol}$).
