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?

5 ml of a gas containing only carbon and hydrogen were mixed with an excess of oxygen (30 ml) and the mixture exploded by means of an electric spark. After the explosion, the volume of the mixed gases remaining was 25 ml. On adding a concentrated solution of potassium hydroxide, the volume further diminished to 15 ml of the residual gas being pure oxygen. All volumes have been reduced to N.T.P. Calculate the molecular formula of the hydrocarbon gas.

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.

30 mL of a mixture of CO and CO_(2) , mixed with 10 mL of oxygen, was exploded by electric spark. The gas mixture produced was mixed with KOH solution and thoroughly shaken. 5 mL of oxygen was left behind. What was the composition of the original mixture [volume was measured at STP].

A mixture of 15 ml of CO & CO_2 is mixed with V ml (excess) of oxygen and electrically sparked. The volume after explosion was found to be (V+12) ml. What would be the residual volume if 25 ml of the original mixture is exposed to an alkali?

A mixture of 15 ml of CO & CO_2 is mixed with V ml (excess) of oxygen and electrically sparked. The volume after explosion was found to be (V+12) ml. What would be the residual volume if 25 ml of the original mixture is exposed to an alkali?

The volume of the gas mixture obtained by passing 400 mL CO_(2) over red hot coke was measured to be 600 mL. find the compo-sition of the gas mixture.

5 " mL of " a gas A containing only C and H was mixed with an excess of O_2 (30 mL) and the mixture was exploded by means of electric sperk. After explosion, the remaining volume of the mixed gases was 25 mL. On adding a concentrated solution of KOH, the volume further diminished to 15 mL. The residual gas was pure oxygen, The molecular formula of the gas A is.
