Exam 2 Equations Molality of solute ( m ) = mol solute kg solvent Mole fraction of A ( X A ) = n A n A + n B + n C + Weight % A = mass of A mass of A + mass of B + mass of C + Henry’s Law S g = k H P g where S g is the solubility of the gas, k H is a constant, and P g is the partial pressure of the gaseous solute Raoult’s Law P solvent = X solvent solvent where P° solvent is the vapor pressure of the pure solvent Mole fraction of solvent ( X solvent ) = n solvent n solvent + (n solute x i) Elevation in boiling point T BP = T F - T I = m solute x k BP x i Freezing point depression T FP = T F - T I = m solute x k FP x i
