Hello I am stuck in my laboratory, I already did the whole procedure, I am in the last step (# 9) but I can't understand that I have what data I have to put in the test data (Theoretical solubility of NaCl, Temperature, Source) could you explain that data I must put, here is all my lab Thank you very much. Test Data: Mass of empty 250-mL beaker: 100.7 g Mass of 250-mL beaker and saturated NaCl solution :106.4 g Temperature of saturated NaCl solution: 24.1°C Mass of 250-mL beaker and NaCl residue (1st weighing): 102.7 g Mass of 250-mL beaker and NaCl residue (2nd weighing): 102.2 g Mass of 250 mL beaker and NaCl residue (3rd weighing): 101.9 g (Use the lowest mass for calculations)

Introduction:
The amount of salt for the preparation of saturated solution is the solubility of salt. The solubility is measured at a specific temperature. The solubility is measured as the grams of solute per 100 g of solvent.
Procedure: Take a certain amount of salt in a beaker filled with water at a particular temperature and make a saturated solution by shaking then filter the saturated solution and measured the residue which has still present in the beaker after filtration.
