12. If you mix 2g of salicylic acid with 20 mL. of t-butyl alcohol Which substance is the solvent and which one is the solute in this experiment? 13. Calculate the molarity and the molality of a solution prepared by dissolving 3.60 g of ethanol (C2HsOH) with 100.0 g of water to give a final volume that is 102 mL 14. What is the freezing point of the solution when 15.00 g of ethylene glycol (C Hs02) is dissolved in 148.0 g of pure water? (The freezing point depression constant for water is 1.86 °C-kg/mol). 15) A solution containing 10.0 g of an unknown liquid and 90.0 g water has a freezing point of- 3.33 C. Given Kf 1.86°C/m for water, the molar mass of the unknown liquid is g mol
