Analyze the graph to describe the solubility of barium nitrate, BaNO3.

At 60°C,_ (100g, 200g, 350g) must be added to 1 L of water to make a saturated solution.
At 25°C, the solubility is about _ .(100 per L, 125 per L, 150 per L)
A solution that contains 600 g BaNO3 in
3 L of H2O at 70°C is _. (saturated, supersaturated, unsaturated)
For a solution that contains 300 g BaNO3 in 3 L of H2O at 60°C to become saturated, _ (100,200,300)g solute must be added.
