- A solution was prepared by dissolving 0.800 g of sulfur, Sg, in 100.0 g of acetic acid, HC2H3O2. Calculate the freezing point and boiling point of the solution.arrow_forwardWhat is the usual solubility behavior of an ionic compound in water when the temperature is raised? Give an example of an exception to this behavior.arrow_forwardWhat is the boiling point of a solution of 9.04 g of I2 in 75.5 g of benzene, assuming the I2 is nonvolatile? (a) Outline the steps necessary to answer the question. (b) Answer the question.arrow_forward
- Vodka is advertised to be 80 proof. That means that the ethanol (C2H5OH) concentration is 40% (two significant figures) by volume. Assuming the density of the solution to be 1.0 g/mL, what is the freezing point of vodka? The density of ethanol is 0.789 g/mL.arrow_forwardWhich of the following will have the lowest total vapor pressure at 25C? a. pure water (vapor pressure = 23.8 torr at 25C) b. a solution of glucose in water with C6H12O6=0.01 c. a solution of sodium chloride in water with NaCl = 0.01 d. a solution of methanol in water with CH3OH=0.2 (Consider the vapor pressure of both methanol [143 torr at 25C] and water.)arrow_forwardA 1.00 mol/kg aqueous sulfuric acid solution, H2SO4,freezes at 4.04 C. Calculate i, the vant Hoff factor,for sulfuric acid in this solution.arrow_forward
- Concentrated hydrochloric acid contains 1.00 mol HCl dissolved in 3.31 mol H2O. What is the mole fraction of HCl in concentrated hydrochloric acid? What is the molal concentration of HCl?arrow_forwardDistinguish between dispersion methods and condensation methods for preparing colloidal systems.arrow_forwardFructose, C6H12O6, is a sugar occurring in honey and fruits. The sweetest sugar, it is nearly twice as sweet as sucrose (cane or beet sugar). How much water should be added to 1.75 g of fructose to give a 0.125 m solution?arrow_forward
