Real Volume of solvent


Recommended Posts

I'm not sure. I have a glass of 450 milliliter solvent. In this solvent are 5.40 g NaOH. The concentration is 0.300 mol / g. Are the 450 milliliters the volume of the solvent alone, or is it the volume of the solvent when NaOH is already present? And if it’s both, how can I find out the volume only of the solvent?
Thanks for your anwsers

Water is solvent.

Water + dissolved NaOH is solution.

Mass of solvent and mass of dissolved substance add together in solution (quantum scale of mass is lost or gained if reaction is exothermic/exoenergetic or endothermic/endoenergetic).

With volume it is no so simple.
