title: Measurement of the density of CO(2) solution by Mach-Zehnder interferometry.
abstract: The density of CO(2) solution was measured by using Mach-Zehnder interferometry in the pressure range from 5.0 to 12.5 MPa, at temperatures from 273.25 to 284.15 K, and CO(2) mass fraction in solution up to 0.061. It was found that the density difference between the CO(2) solution and pure water at the same pressure and temperature is monotonically linear with the CO(2) mass fraction. The slope of this linear function, calculated by experimental data fitting, is 0.275.
