A solution containing 7.8 g of a nonvolatile, nondissociating substance dissolved in 1.00 mol of chloroform, CHCl3, has a vapor pressure of 524 torr. The vapor pressure of pure CHCl3 at the same temperature is 540 torr. Calculate (a) the mole fraction of the solute, (b) the number of moles of solute in the solution, and (c) the molecular mass of the solute.
The Henry's law constant for helium gas in water at 30°C is 3.7 10-4 M/atm; that for N2 at 30°C is 6.0 10-4 M/atm. If the two gases are each present at 1.2 atm pressure, calculate the solubility of each gas. What is the Molarity of He and N2

A liquid unknown was found to be insoluble in water and soluble in cyclohexane and alcohol; the unknown was found to have a boiling point of 58 degrees C at 670mm Hg
Predicting the Polarizability of a Molecule. Consider the following set of data for polarizability. From what I have learned, the simplest model for predicting the polarizability of a molecule is to assume that polarizability scales with the type.
what is the molality of ethanol in a solution made by dissolving 14.6g of ethanol, C2H5OH, in 53.6 g of water?
