need help please understanding this question!!
Experiments show that the solubility of alum under conditions used in this lab is about 1.0g at 1.0 c and 1.7 at 6.0 c. Using your measured solution temperature, estimate the amount of alum left in your chilled solution according to the graph. Thank you very much!! I have no idea how to set it up and in case this shows up on an exam, I want to know how to do it!! Thank you!!!!

1. Experiments show that the solubility of alum under the conditions used in this lab is about 1.0 g
at 1.0 °C and 1.7 g at 6.0 °C. Using your measured solution temperature, estimate the amount of
