Ko for water is 0.512 mºC. What is the boiling point after 75 grams of water evaporated? 16. What is the molality of a 5.117 M solution of phosphoric acid with a density of 1.254 g/mL? = 17. The vapor pressure of a mixture of 400 g of carbon tetrachloride (CCl4, MM = 153.81) and 43.3 g of an unknown compound is 133 torr at 30 °C. The vapor pressure of pure carbon tetrachloride at 30 °C is 143 mmHg. What is the molar mass of the unknown? 18. MTBE (methyl t-butyl ether) is an octane booster. Octane in gasoline is related to the compound 2, 2, 4 trimethyl pentane. Using the data below (tabulated at 25 °C), what is the vapor pressure, in kilopascals (kPa), of a fuel mixture formed by mixing 3.30 mol of MTBE (CsH120) with 2.73 mol of 2, 2, 4 trimethyl pentane (octane in gasoline-C8H18) at 25 °C? Assume ideal behavior. Compound Vapor pressure of pure, mmHg MTBE 27.0 2, 2, 4 trimethylpentane 5.1 19. Arrange the following substances in order of increasing (smallest = 1, largest = 6) Van't Hoff factor (l) when dissolved in water. Assume ideal behavior.
