Molar mass of NaCl (Sodium chloride)
The molar mass of NaCl is 58.44 g/mol.
Common table salt, made when hydrochloric acid neutralises sodium hydroxide.
Step-by-step calculation
Add up the atomic masses of every atom in the formula:
1 × 22.99 + 1 × 35.453 = 58.44 g/mol
| Element | Atoms | Atomic mass (u) | Subtotal (g/mol) | % by mass |
|---|---|---|---|---|
| Sodium (Na) | 1 | 22.99 | 22.990 | 39.34% |
| Chlorine (Cl) | 1 | 35.453 | 35.453 | 60.66% |

Moles to grams for NaCl
Multiply the number of moles by 58.44 g/mol to get the mass, and divide a mass by 58.44 g/mol to get the moles.
| Amount (mol) | Mass (g) | Mass (g) | Amount (mol) |
|---|---|---|---|
| 0.1 mol | 5.84 g | 1 g | 0.0171 mol |
| 0.25 mol | 14.61 g | 5 g | 0.0856 mol |
| 0.5 mol | 29.22 g | 10 g | 0.1711 mol |
| 1 mol | 58.44 g | 50 g | 0.8555 mol |
| 2 mol | 116.89 g | 100 g | 1.7111 mol |
| 5 mol | 292.21 g | 500 g | 8.5553 mol |
