Calculate with reference to the actual total volume of solvent used, the amount of acetanilide and benzoic acid that is recoverable because of their solubilities at 0 C (celsius).It is desired to determine the molecular weight of an organic compound known to be volatile. For this, a glass balloon with a full volume of 152 mL is weighed and the weighing result is recorded as 215 g. Then, the organic compound that is desired to have some molecular weight in liquid form is added into the balloon and evaporated in a water bath until dryness. After the steam temperature is measured as 90 °C, the balloon is left to cool and the organic compound in the balloon condenses again. The balloon is then weighed again and recorded as 215,367g. Find the molecular weight of this organic compound since the pressure of the environment where the experiment is performed is 700 mmHg.
