Calculate the molar mass of any chemical compound by entering its formula. Also convert grams to moles.
g/mol
| Molar Mass | 18.015 g/mol |
| Moles in input mass | 0.9992 mol |
| H (ร2) | 1.008 ร 2 = 2.016 g/mol |
| O (ร1) | 15.999 ร 1 = 15.999 g/mol |

M = ฮฃ (atomic mass ร subscript)
moles = mass (g) / M (g/mol)
Molar mass is the mass of one mole of a substance (6.022ร10ยฒยณ particles), expressed in g/mol. It equals the sum of atomic masses in the formula.
HโO: 2ร1.008 + 15.999 = 18.015 g/mol.
NaCl: 22.990 + 35.45 = 58.44 g/mol.
Add the atomic masses of all atoms in the formula. Multiply each element's mass by its subscript, then sum all values.
