Identity summary

Name Ammonium Chloride
Other names (IUPAC) azanium chloride
Molecular formula NH4Cl
CAS number 12125-02-9
Molar mass 53.49 g/mol
PubChem CID 25517

Molar mass of NH4Cl and how to calculate it

The molar mass of NH4Cl is 53.49 g/mol, the sum of the relative atomic masses of all atoms in the formula: 14.007 + 4 × 1.008 + 35.450 = 53.49 g/mol.

Element Atoms Atomic mass Contribution Mass %
N 1 14.007 14.01 26.19%
H 4 1.008 4.03 7.54%
Cl 1 35.450 35.45 66.28%

So 1 mol of NH4Cl weighs 53.49 g, and 1 L of a 0.1 M solution needs 5.349 g of pure NH4Cl. For liquid or concentrated reagents, work from assay and density with the dilution formula. Calculate other compounds with the molar mass calculator.

What is an MSDS/SDS?

An MSDS (Material Safety Data Sheet), now called an SDS (Safety Data Sheet), is a 16-section document describing the hazards, handling, storage, first aid, and disposal of a chemical. Read the full MSDS guide and other MSDS pages.

This summary was compiled by AMI Scientific from TCI official GHS data for information purposes. Classification may differ by concentration, form, and supplier. Always refer to the manufacturer's official SDS for the product and lot you use. Updated: 06-11-2026.
