(a) Interpretation: The empirical formula for the compound needs to be determined when the mass of the compound is 0.270 g and it is dissolved in 50.0 g of camphor. The freezing point of the resultant solution is 177.9 °C. The freezing point camphor is 179.8°C and K f = 37.7 °C.kg/mol. Also, in the excess of oxygen gas, the combustion of the compound gives CO 2 that completely reacted with 20.0 mL of 2.00 M NaOH. Concept introduction: Colligative properties are the properties that depend on the number of particles present in the solution. Elevation in boiling point, depression in freezing point, lowering in vapor pressure and osmotic pressure are some common examples of colligative properties. Vapor pressure is the pressure at which is exerted by vapor on the liquid surface in a closed system when the system is in thermodynamic equilibrium.
