9.14 The density of a methanol-water solution that is 12.000 weight percent methanol is 0.97942 g/cm³ at 15°C and 1 atm. For a solution that is 13.000 weight percent methanol, the den- sity is 0.97799 g/cm³ at this T and P. Since the change in solu- tion composition is small, we can estimate VA by VA = (av/əna)r.p.n. = (AV/Ana)r.p.n. Calculate V(CH;OH) for a methanol-water solution at 15°C and 1 atm that is 12,% CH,OH by weight. Then calculate V(H,O) for this solution.

If 124.4 mL of water is shaken with oxygen gas at 0.81atm, it will dissolve 0.0036 g O2. Estimate the Henry's law constant for the oxygen gas in water in units of g mL ^-1atm^-1.
Osmotic pressures are often reported in units of atmospheres or mm Hg. The latter impliesthat the height of a column of liquid can be used as a measure of pressure. This is, in fact, thebasis of the torricellian barometer from which the units of “torr” come. The pressure, P, isrelated to the height of the column by:P = ρghwhere ρ is the density of the liquid, g is the acceleration due to gravity and h is the height. Whatwill be the height (in mm) of a column of aqueous solution with a density of 0.9987 g/mL, if theosmotic pressure of the solution at 25 °C is 1.4 mm Hg? The density of mercury at thistemperature is 13.8 g/mL

In the determination of molar mass of an unknown substance by ebullioscopic constant, 30 mL of acetone (C3H6O) was placed in a test tube with thermometer and glass tubing and subjected to water bath. Upon boiling, the temperature reads 56 deg C. For the boiling point of unknown-acetone solution, you prepared the solution by mixing 1.60 g of unknown solute in the 30 mL acetone and subjected it again to water bath.
