Identity summary

Name Urea
Other names (IUPAC) –
Molecular formula CH4N2O
CAS number 57-13-6
Molar mass 60.056 g/mol
PubChem CID 1176

Molar mass of CH4N2O and how to calculate it

The molar mass of CH4N2O is 60.06 g/mol, the sum of the relative atomic masses of all atoms in the formula: 12.011 + 4 × 1.008 + 2 × 14.007 + 15.999 = 60.06 g/mol.

Element Atoms Atomic mass Contribution Mass %
C 1 12.011 12.01 20.00%
H 4 1.008 4.03 6.71%
N 2 14.007 28.01 46.65%
O 1 15.999 16.00 26.64%

So 1 mol of CH4N2O weighs 60.06 g, and 1 L of a 0.1 M solution needs 6.006 g of pure CH4N2O. 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.
