Solubility is the ability to dissolve certain substances(solutes) into a solvent. You are a student in Mrs. Bateast's Chemistry class and you were given the assignment to compare solubilities of salt in different solvents at different temperatures. You added salt at a consistent rate and amount until you reached the point of full saturation. The amount added to each solvent at saturation was recorded. The results of the experiment are shown in the tables: Table 1: 20 °C Mass of Salt at Saturation 43 g 38 g 0.01 g 3 g Solvent Water Ethanol Hexane Dichloromethane Table 2: 35 °C Mass of Salt at Saturation 52 g 45 g 0.02 g 4 g Solvent Water Ethanol Нехane Dichloromethane Using CER and your knowledge from data listed above, if the temperature of ethanol solution increased by an additional 10 degrees, what would happen? Construct a line graph is required as well.

Part C You need to prepare a 2.40 M solution of sodium hydroxide (molar mass of sodium hydroxide = 40.00 g/mol ), but you only have a 10 mL graduated cylinder and a 25 mL beaker. Complete the following sentences regarding the concentration of the prepared solution. Match the words in the left column to the appropriate blanks in the sentences on the right. Make certain each sentence is complete before submitting your answer. • View Available Hint(s) Reset Help greater than 10.0 mL 1. In order to prepare 10.0 mL (0.0100 L) solution of 2.40 M sodium hydroxide, a mass of would be required. exactly 10.0 mL exactly 2.40 M 2. When the solute and a total of 10.0 mL of water are both added into the beaker and stirred until 0.024 g the solute dissolves, the solution volume will be greater than 2.40 M 3. Based on that, the concentration of the prepared solution will be less than 2.40 M. less than 10.0 mL 0.960 g P Pearson
