Product description
- When dissolving 3.00 g of a certain substance in 100 g of carbon tetrachloride CCl4, the boiling point rises by 0.60 K. Calculate the decrease in freezing point, the molar mass of the solute, the relative decrease in the pressure of saturated vapor CCl4 (p0-p)-p0 and osmotic solution pressure at 25 C, if the cryoscopic constant of 31.8 K * kg / mol and the ebullioscopic constant of 5.03 K * kg / mol are known for the solvent. Take the ideal solution and its density at 25 C equal to the density of pure CCl4 1.595 g/cm3.
