Why is there a degrees sign for celcius and fahrenheit, but not for kelvin? i understand that you don't actually say "degrees kelvin" out loud, but i still don't really know why. my teacher said something about it being an absolute temperature scale, but that kind of confused me more. can anyone explain?

Achemistry student needs to standardize a fresh solution of sodium hydroxide. he carefully weighs out of oxalic acid , a diprotic acid that can be purchased inexpensively in high purity, and dissolves it in of distilled water. the student then titrates the oxalic acid solution with his sodium hydroxide solution. when the titration reaches the equivalence point, the student finds he has used of sodium hydroxide solution.calculate the molarity of the student's sodium hydroxide solution. be sure your answer has the correct number of significant digits.
