An unsaturated solution is made by completely dissolving 20.0 grams of NaNO3 in 100.0 grams of water at 20.0°C. (the gram formula mass=85.0 grams per mole)
Determine the minimum mass of NaNO3 that must be added to this unsaturated solution to make a saturated solution at 20.0°C.
I haven't been taught this yet but i want to get a head start. So, I am reviewing the regent questions from the website.
Thank you very much for the help
