AI Thread Summary
Molar density can be calculated using the formula molar density = temperature / (given temperature * 22.4). In the example provided, this results in a calculation of 0.0331 kg mol/m^3. The value 22.4 represents the molar volume of an ideal gas at standard temperature and pressure (STP). The final units of molar density can be expressed as either kg mol/m^3 or mol/m^3, depending on the context. Understanding the relationship between temperature and molar volume is essential for accurate calculations.

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.
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
