Calculate the volume of `O_(2)` gas requried for complete burning of 10 L of acetylene gas. Also calculate the volume of `CO_(2)` produced. All volumes are measured at same temperature and pressure.

Calculate the volume of O_(2) at STP required to completely burn 100 ml. of acetylene.

Calculate the volume of O_(2) at STP required to burn completely 70 ml of acetylene.

How many litres of oxygen at STP are required for the combustion of 4 g of methane gas? Also calculate the volume of CO_(2) gas produced at STP.

How many litres of oxygen at STP are required for the combustion of 4 g of methane gas? Also, calculate the volume of CO_(2) gas produced at STP.

Combustion of 1 volume of a compound (contains of C, H and N) in air produces 3 volumes of CO_(2) and 4.5 volumes water vapour and 0.5 volume of N_(2) . Calculate the molecular formula of the compound. [all volumes are measured at same temperature and pressure].

Air contains 20% oxygen by volume. Calculation the theoretical volume of air which will be required for burning completely 200 cubic m of acetylene gas (C_(2) H_(2)) All volumes are measured under the same conditions of temperature and pressure.
