SUMMARY

The formula for calculating molar density is defined as molar density = temperature / (given temperature * 22.4). In the example provided, the calculation is performed as molar density = 273 / (368 * 22.4), resulting in a value of 0.0331 kg mol/m³. The constant 22.4 represents the molar volume of an ideal gas at standard temperature and pressure (STP), which is critical for deriving the final units of kg mol/m³ or mol/m³.

PREREQUISITES
  • Understanding of ideal gas laws
  • Familiarity with standard temperature and pressure (STP) concepts
  • Basic knowledge of unit conversions in chemistry
  • Proficiency in algebraic manipulation of formulas
NEXT STEPS
  • Research the ideal gas law and its applications in chemistry

how do you calculate molar density?
in one solution it is calculated as molar density = temperature / (given temperature(which is 95C) * 22.4)
in other words it is molar density = 273/(368 x 22.4) = 0.0331 kg mol /m^3
i don't know which formula is this and what is 22.4? and how they end up with the final units

\frac {kg \times mol} {m^3} or \frac {mol} {m^3}?

22.4 looks like a molar volume of an ideal gas at STP.
