Highest molarity possible?
« on: January 20, 2009, 08:36:12 PM »
I was going through my notes over the year, and my eye caught one that was rather suspicious. My teacher taught us that an 18 molar solution is actually 100% solute. I thought about this for a minute, and I realized, "Isn't molarity a ratio of moles of solute to liters?" So, wouldn't molarity be based on the volume of the substance per mole, and the maximum molarity dependent on the density of the substance, or does it depend on its solubility in water (otherwise the solvent) too?

Thanks for your replies in advance.

Dear mgyucht;

You are right! - It's mole per Liter.
For example 1.0 Liter pure water is 55.55 molar at room temperature.

Good Luck!

Thank you ARGOS++, I finally understand it. It has to do with the molar mass of the molecule/compound rather than being on a scale from 0-18.
