If 75grams of KNO3 are dissolved in 100 grams of H2O at 45 degrees Celsius, what level of saturation is in the soultion.

Do you have a graph in your text or in your notes giving the solubility at various temperatures? If so, look on the graph, determine the solubility at 45 degrees C, then 75/value from graph fractional saturation.
