Molar Mass Calculator

One mole of any substance contains 6.022×10²³ particles - Avogadro's number

Water's molar mass (18.015 g/mol) means 18g of water has 6×10²³ molecules

Helium (4 g/mol) is so light it escapes Earth's atmosphere over time

Diamond and graphite have the same molar mass (12 g/mol) - both are pure carbon

Hemoglobin has a molar mass of ~64,500 g/mol - proteins are huge molecules

Buckminsterfullerene (C60) has exactly 720.64 g/mol - a perfect carbon sphere

Aspirin (C9H8O4) has a molar mass of 180.16 g/mol - memorized by pharmacists

Uranium (238 g/mol) is the heaviest naturally occurring element
