You are handed a 15.85% by mass aqueous KCl (m.m. = 74.5513 g mol–1) solution (at 25 °C). Assume the density of the solution is that of pure water (dsolution = 1.000 g mL–1). The ebullioscopic constant (Kb) for water is 0.513 °C m–1. The cryoscopic constant (Kf) for water is 1.86 °C m–1. The vapor pressure of pure water is 0.0313 atm. Determine the following: Boiling Point in degrees Celcius
During the solution process, there are four different interacting forces involved: Hydrogen Bonding, Dipole-Dipole Forces, Van Der Waals forces, and London Dispersion Forces. Briefly explain each.

Due to the fact that the liquid you used was a volatile one, it will not completely recondense. Some of the liquid remains in the vapor phase, even at room temperature. If you were able to correct for this by making the vapors recondense completely, would your final molar mass value be greater than, less than or the same as the value you determined? Explain your reasoning.
