What is meant when someone says 50% solution of NaCl?
when someone talks about a 50% NaCl solution or a 35% ethylene glycol solution, what does this really mean? Is this the percentage of the solute in the solution by mass, moles, or what?

In reality volumes don't add, but 99% of the time for lab purposes it doesn't matter if you're off by 0.01 mL.
