Question

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 (d_solution = 1.000 g mL^–1).

The ebullioscopic constant (K_b) for water is 0.513 °C m^–1.
The cryoscopic constant (K_f) for water is 1.86 °C m^–1.
The vapor pressure of pure water is 0.0313 atm.

Determine the following:
