I need to figure out whether NaNO3 is saturated, unsaturated, or supersaturated in a 3 molal solution at 40 degrees Celsius. I am completely stuck right now, and am not sure where to go with this.

Do you have a table or a graph in your text/notes that gives the solubility of NaNO3 at 40 C?
DrBob222,
No. We have used the Solubility Curve before, but it doesn't show NaNO3 at 40 C. All I have is the 3m, 40 C, and you can figure out the molar mass (85). Any idea how to go about this?

See this link. I would read that as 105 g NaNO3/100 g H2O

So mols NaNO3 = 105 g/85 = about 1.2 and
1.2 mol/0.1 kg solvent = about 12 m. So 3 m should be .......?
