Quick question regarding solution concentrations

AI Thread Summary
The concentration of Na in a solution of NaCl at 0.1M is indeed 0.1M, as each NaCl unit dissociates into one Na ion. In the case of Na2Cl, a 0.1M concentration would result in a Na concentration of 0.2M, since each formula unit provides two Na ions. The discussion highlights the importance of understanding the relationship between molarity and the number of ions produced in solution. Normality, which accounts for reactive species in a solution, differs from molarity, which is simply the concentration of solute. Understanding these concepts is essential for accurate calculations in chemistry.

If you had a compound, say NaCl, with a certain concentration in water. Would the concentration, in mols/volume, be the same for Na as for NaCl?

if the concentration for NaCl was .1M, the concentration of Na would be .1M as well?

And if you somehow had Na2Cl with a .1M concentration, would the concentration of Na be twice that of Na2Cl?

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...
