You need a graph of saturation concentration (in units of g/100 cc) along the y axis vs temperature (plotted on the x axis). Look up the temperature on the curve that corresponds 50 g/100 cm^3. That will be the answer.
According to data in my Chem Physics handbook, the saturation concentration of KNO3 in H2O is 50 g/100 cm^3 at about 40 C. I only have data points at 0, 20 and 100 C, and so should plot a curve for a more accurate value.
