See the first 4 situations marked on the attached graph.
___________________________________

In #4, we ( I ) discovered that at 30°C, 40-something grams of KNO₃
can dissolve in 100 grams of water.

Then, #5 says that 60 grams of KNO₃ are dissolved in water
at that temp, but it doesn't say how much water !

-- If it's 2 drops of water, then it's way supersaturated.

-- If it's an olympic-size swimming pool, then it's unsaturated.

We can't tell, because we don't know how much water.

1) NaNO3
2) KNO3 
3) 43g
4) 40g
5) Super saturated.
