colligative properties 2 The solution will have a lower vapor pressure than the pure solvent. 3 NaCl because it produces fewer moles of solute particles per mole of compound. 4 (1.50 mol) / (0.250 kg) = 6.00 mol/kg = 6.00 m 5 (300 g H2O) / (18.01532 g H2O/mol) = 16.652 mol H2O
(750 mmHg) x (16.652 mol / (16.652 mol + 0.27 mol)) = 740 mmHg 6 0.0°C 7 101.7°C 8 vapor pressure
