Conclusion section. Write a coherent paragraph that addresses the tollowing: - Does KNO3 have an endothermic or exothermic heat of solution? Justify your answer based on your experimental evidence. - Do the literature solubilities shown above lie on your experimental solubility curve? If not, use the direction of the error in your solubility curve (whether it is above or below the literature values) to propose one or more likely sources of error - consider possible changes in (or errors in measuring) the masses of water and KNO3 as well as the detection of the saturation temperature
