Molar mass
Molar mass. The mass of one mole in grams: add the atomic mass of every atom in the formula. Masses. Standard atomic masses to two decimals, hydrogen 1.008, every element to uranium. Typing. Ca(OH)2, (NH4)2SO4, CuSO4.5H2O and K4[Fe(CN)6] all work.

1 mol of NaCl = 6.022 × 10²³ formula units
At 1 atm (older value): 22.40 L
Add up the atoms
- Sodium: 1 × 22.99 = 22.99 g
- Chlorine: 1 × 35.45 = 35.45 g
- Molar mass = 22.99 + 35.45 = 58.44 g/mol
