What's the solubility of KNO3 per 100 g H2O for the temperature of 67.8 degrees Celsius.What is the solubility at this temperature? What is Ksp? Please advise. It said to refer to a graph of solubility in the text, but I could not find it for this compound. A link to a graph would be nice, thank you.

Looks like 120g/100g H20 but you will have to interpolate for an accurate value for 67.8
molar mass =101.1g/m
120g/101.1g/m=1.19m not being into partial molal volumes, I will have to do some creative calculations. 120g/100g H2O Weighs about 220g but can not determine volume without measuring or with calculus. So we will guess about 150 ml because the density would be about 1.5g/ml.
So 1.19mKNO3/0.150L=7.9M Ksp = [K+] [NO3 -1] =7.9^2= 62 @67.8 deg which makes sense the more soluble the higher The Ksp
