A gaseous mixture of propane and butane of volume 3 litre on complete combustion produces 11 lit `CO_(2)` under standard condition of temp. and pressure. Find the ratio of volume of butane to propane.

3L Mixture of propane and butane on complete combustion at 298K and 1atm gave 10L CO_2. Calculate the composition of gas

The volume of O_(2) required for the combustion of 10 lit of methane under the same condition is

If 2 litres of butane is completely burnt the volume of CO_(2) obtained under the same conditions would be

One litre of a mxiture of CO and CO_(2) is passed over red hot coke when the volume increased to 1.6 L under the same conditions of temperature and pressure . The volume of CO in the original mixture is

The volume of oxygen required at STP for the complete combustion of 2.2 g of propane

A gas mixture contains acetylene and carbondioxide. 20 lit of this mixture requires 20 lit of oxygen under the same conditions for complete combustion. The percentage by volume of acetylene in the mixture is

40 ml of a hydrocarbon undergoes combustion in 260 ml oxygen and gives 160 mlof CO_(2) . If all volumes are measured under similar conditions of temperature and pressue, the formula of the hydrocarbon is
