A 1.0g sample of a pure organic compound cotaining chlorine is fused with `Na_(2)O_(2)` to convert chlorine to NaCl. The sample is then dissolved in water, and the chloride precipitated with `AgNO_(3)`, giving 1.96 g of AgCl. If the molecular mass of organic compound is 147, how many chlorine does each molecule contain ?

A solution containing 1.332 g of CrCl_(3).6H_(2)O is passed through a cation exchange. The chloride ions in solution was precipitated with excess AgNO_(3) to give 1.43 g of residue. How many water molecules are in the coordination sphere ?

1 g of an organic compound containing oxygen is heated with graphite and carbon monoxide formed is quantitatively converted to 0.1375 g CO_(2) on reaction with I_(2)O_(5) calculate the percentage of oxygen in the compound.

0.36g of an organic compound on combustion gave 1.1g of CO_(2) and 0.54g of H_(2)O . The percentages of carbon and Hydrogen in the compound are

0.25 g of an organic compound was found to produce 0.35 g of AgCl after heating with fuming HNO_(3) and AgNO_(3) in a sealed carius method. Determine the percentage of chlorine in the compound.

0.2g of an organic compound on analysis give 0.147g of carbondioxide, 0.12 g of water and 74.6 c,c of nitrogen at S.T.P. Calculate the weight percentages of constituents.

A basic volatile compound gave a foul smelling gas when treated with CHCl_(3) and alc. KOH. A 0.295 g sample of the substance dissolved in aqueous HCl and treated with NaNO_(3) solution at 0^(@)C liberated a colourless, odourless gas whose volume corresponds to 112 ml at STP. After the evolution of gas was complete, the aqueous solution gave an organic liquid which did not contain nitrogen and on boiling with I_(2) in the presence of alkali gave a yellow precipitate. The molecular weight of the basic volatile compound is
