0.378 g of an organic compound containing carbon and hydrogen was subjected to combustion by Liebig's method , the CO_(2) and H_(2)O formed were passed through potash bulbs and CaCl_(2) (anhydrous) tube. At end of the experiment, the increase in the respective weights were 0.264 g and 0.162 g. Calculate the percentage of carbon and hydrogen.

Lowering in vapour pressure is determined by Ostwald and Walker dynamic methed. It is based on the prinicipal , that when air is allowed to pass through a solvent or solution, it takes up solventvapour with it to get itself saturated at that temperature I and II are weighted separately before and after passing dry air. Loss in mass of each set, gives the lowing of vapour pressure. The temperature of air, the solution and the solvent is kept constant. Gain in mass of anhydrous CaCl_(2) is proportional to :

Loss in mass of each set, gives the lowing of vapour pressure. The temperature of air, the solution and the solvent is kept constant. Dry air was passed thorough 9.24 g of solute in 108 g of water and then through pure water. The loss in mass of solution was 3.2 g and that of pure water 0.08 g . The molecular mass (g/mol) of solute is nearly : (a)50 (b)62 (c)70 (d)80

A current of dry air was bubbled through in a bulb containing 26.66g of a n organic substance in 200gms of water, then through a bulb at the same temperature containing pure water and finally through a tube containing fused calcium chloride. The loss in weight of water bulb is 0.0870 gms and gain in weight of CaCl_(2) tube is 2.036 gm. Calculate the molecular weight of the organic substance in the solution.

Read following statement(s) carefully and select the right option : (I) The enthalpy of solution of CaCl_(2). 6H_(2)O in a large volume of water is endothermic to the extent of 3.5 kcal/mol. If DeltaH=-23.2 " kcal" for the reaction, CaCl_(2)(s)+6H_(2)O(l)rarrCaCl_(2).6H_(2)O(s) then heat of solution of CaCl_(2) (anhydrous) in a large volume of water is - 19.7 kcal/mol (II) For the reaction 2Cl(g)rarrCl_(2)(g) , the sign of DeltaH and DeltaS are negative.
