Molar Mass of Sodium bicarbonate
NaHCO3 — 84.006 g/mol, worked out element by element.
Molar mass of Sodium bicarbonate, NaHCO₃
84.006 g/mol
Molecular weight 84.006 · 6 atoms per formula unit
Also known as: nahco3, baking soda, sodium hydrogen carbonate.
Baking soda: releases CO₂ on heating or on meeting an acid, which is what makes cakes rise.
How 84.006 g/mol is worked out
| Element | Atoms | Atomic mass | Mass | % of total |
|---|---|---|---|---|
| Oxygen | 3 | 15.999 | 47.997 | 57.14% |
| Sodium | 1 | 22.99 | 22.990 | 27.37% |
| Carbon | 1 | 12.011 | 12.011 | 14.30% |

Frequently Asked Questions
What is the molar mass of Sodium bicarbonate?
The molar mass of Sodium bicarbonate (NaHCO3) is 84.006 g/mol. That is the sum of the standard atomic weights of all 6 atoms in one formula unit: 3 × 15.999 + 1 × 22.990 + 1 × 12.011 + 1 × 1.008 = 84.006.
What is the molecular weight of Sodium bicarbonate?
84.006 — the same number as the molar mass, but as a dimensionless ratio rather than in g/mol. The two terms describe the same arithmetic, so a molecular weight of 84.01 and a molar mass of 84.01 g/mol are the same answer.
How many moles are in 100 g of Sodium bicarbonate?
100 ÷ 84.006 = 1.1904 mol. To convert any mass to moles, divide by the molar mass; to go the other way, multiply.
What is the percent composition of Sodium bicarbonate?
By mass, Sodium bicarbonate is 57.14% oxygen, 27.37% sodium, 14.30% carbon, 1.20% hydrogen. Each element's share is its total mass in the formula divided by 84.006.
How many atoms are in one formula unit of Sodium bicarbonate?
6: 3 oxygen, 1 sodium, 1 carbon, 1 hydrogen. One mole contains 6.02214076 × 10²³ formula units, so a mole of Sodium bicarbonate contains 6 × 6.022 × 10²³ atoms in total.
