How much salt is there in a sample which weighs 150 grams? а. 1.2 g b. 19.5 g c. 30.0 g d. 7.5 g 3. What is the molarity of KI in a solution that is 5.00% KI by mass and has a density of 1.038 g.cm3? b. 0.313 M c. 0.500 M d. 0.625 M a. 0.0301 M 4. In a heating or cooling curve, what does it mean when the line stays flat for a while before going up or down? 5. Consider a solution composed of toluene (C7He) and benzene (C6H6) with volumes 50 mL and 125 mL, respectively. The densities of the compositions are 0.867 g/cm3 and 0.874 g/cm³, respectively. Find the molarity with respect to toluene.
