What is the formula for calculating water vapor density?

What are the formulas for calculating water vapor density? There are IFC67 and IFC97 formulas – what type of steam are they suitable for? Saturated steam? Superheated steam? Does it apply to all of them?

Come to learn*. Generally, the ideal gas equation of state is used: PV=nRT; therefore, PV=mRT/M. Also, PM=ρRT, so ρ=RT/PM. Alternatively, software such as ASPEN can be used for simulation.
