Identity summary

Name Citric Acid
Other names (IUPAC) 2-hydroxypropane-1,2,3-tricarboxylic acid
Molecular formula C6H8O7
CAS number 77-92-9
Molar mass 192.12 g/mol
PubChem CID 311

Molar mass of C6H8O7 and how to calculate it

The molar mass of C6H8O7 is 192.12 g/mol, the sum of the relative atomic masses of all atoms in the formula: 6 × 12.011 + 8 × 1.008 + 7 × 15.999 = 192.12 g/mol.

Element Atoms Atomic mass Contribution Mass %
C 6 12.011 72.07 37.51%
H 8 1.008 8.06 4.20%
O 7 15.999 111.99 58.29%

So 1 mol of C6H8O7 weighs 192.12 g, and 1 L of a 0.1 M solution needs 19.212 g of pure C6H8O7. 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.
