a Indicate the solubility of the following solutes in 100 g of water: potassium chlorate at 90 C KClO3= 49g b.

Sodium nitrate (NaNO3) was added to 2.0 L of water at 25 °C to produce a saturated solution. The solution was then heated to 80 °C. Calculate the mass of sodium nitrate that had to be added to produce a saturated solution at that higher temperature
