what mass of precipitate will form if a saturated solution of potassium nitrate is dropped from a temperature of 70 degrees celsius to a temperature of 45 degrees celsius?

Do you have anything (a graph, table, etc) that tells you (or allows you to obtain) the solubility of KNO3 at 70 C and 45 C?

Test Tube # Gram of KNO3 + ml of H2O Crystallization temp. (oC)
1 6.00g/10ml 50 oC
2 9.00g/10ml 54 oC
3 12.00g/10ml 65 oC
4 15.00g/10ml 72 oC
