Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

The density of ozone was calculated with the Ideal Gas Law: p*V = n*R*T using also n = m/M and ρ = m/V.

p = pressure [Pa]

V = Volume [m³]

n = amount of substance [mol]

R = gas constant [J/(mol*K)]

T = temperature [K]

m = mass [kg]

M = molecular weight [g/mol]

ρ = density [g/m³]

Conclusions:
The density of ozone gas is 1.962 g/L according to the CRC Handbook of Chemistry and Physics 92nd Edition (2011). The density was calculated with the Ideal Gas Law.
Executive summary:

The density of ozone gas is 1.962 g/L according to the CRC Handbook of Chemistry and Physics 92nd Edition (2011). The density was calculated with the Ideal Gas Law.

Description of key information

The density of ozone gas is 1.962 g/L at 25 °C according to the CRC Handbook of Chemistry and Physics 92nd Edition (2011) and was calculated with the Ideal Gas Law.

Key value for chemical safety assessment

Relative density at 20C:
