10 mL of a gaseous organic compound composed off carbon, hydrogen and oxygen is mixed with 100 mL of oxygen and subjected to explosion. Volume of the mixture produced by explosion when cooled becomes 90 mL. on treatment with KOH, the volume is reduced by 20 mL. mass of 1 L of gaseous organic compound is 2.053 g at STP. determine the molecular formula.

5 mL of a gas composed of hydrogen and carbon is mixed with 30 mL of oxygen and exploded with electric sparking. The volume of the gas mixture, obtained by explosion is found to be 25 mL. KOH is then addded to the mixture and as a result, its volume is reduced to 15 mL. the residual gas is purely oxygen. all volumes have been measured at STP. what is the molecular formula of the gas?

A gaseous hydrocarbon of volume 10 mL at STP is mixed with 80 mL of O_(2) and burnt completely. As a result, the volume of the gaseous mixture was reduced to 70 mL. on treating the obtained gaseous mixture with KOH solution, the volume becomes 50 mL. determine the molecular formula of the hydrocarbon.

When 3 volume of a gaseous organic compound of carbon, hydrogen & sulphur mixed with excess oxygen is exploded, 3 volumes of carbon dioxide, 3 volumes of sulphur dioxide and 6 volumes of water vapour are produced. What is the formula of the compound?

60 mL of a mixture of CO and H_(2) , mixed with 40 mL of O_(2) , are subjected to explosion in a eudiometer tube. On cooling the gas mixture after the end of the reaction, the volume is reduced to 30 mL. determine the compostion of the gas mixture initially taken. [All volumes are measured at the same temperature and pressure].
