One potential problem with using molarity to express concentration is that molarity is temperature dependent. If you make a 1.000 M solution of aqueous HCl at 25 degrees celsius, what would the molarity of this solution become if the temperature of the solution is elevated to 97 degrees celsius?

Is there an equation that I can use that has concentration and temperature together?
