When a sample of baking is strongly ignited in a crucible, it suffered a loss in weight of 3.1 g. The mass of baking soda is

A current of dry air is passed through the above apparatus containing two sets of bulbs . One set of bulbs is filled with the solution and second with the solvent . Finally that is attched with a U-tube containing CaCl_(2) , which is very efficient in absorbing the water vapour. Passing of dry air through all these three causes some change in weight. Dry air was passed through solution of 5g of solute in 80g of water and the passed thriugh pure water . The loss in weight of solution was 2.5g and that of pure water was 0.04g . The molecular mass of solute is

10g of a mixture of CaCO_(3) and Na_(2)CO_(3) on ignition suffered a loss in weight of 2.2g. The mass ratio of CaCO_(3) and Na_(2)CO_(3) is

A body of mass 15 g oscillates about a fixed point with a SHM of amplitude 8cm . If the body is attracted towards the fixed point, when at a distance of 4 cm from it with a force equal to the weight of 10 g , the period of oscillation of the mass about the fixed point is

Loss of weight will be seen in this disease.

Set A of glass bulbs contain a solution of 1 mole of glucose in 24 mol of water . Another set B of bulbs contain pure water . All bulbs are maintanined at the same temperature and are interconnected as then through pure water in set B. The solution is found to suffer a mass loss of W_(1)g and water suffers a mass loss of W_(2)g afetr certain period of time . If vapour pressure of water is 50 mm Hg at the temperature of experimeter, the vapour pressure of solution will be :
