Theoretical density of co2
WebbThe density of a material is the mass contained in a unit volume. The unit of density is kg/m 3 or lb/in 3. The formula for density is p = m/V, where p is the density, m is the mass and V is the volume. For solid materials, density decreases with increasing temperature.
