Question

A volume of mixture consisting of a gaseous organic compound A and just sufficient amount of oxygen ids required for complete combustion yielding on burning 8ml of co2 , 12ml of water and 4ml of N2. All volume are measured at same temperature and pressure. The compound A contains only carbon , hydrogen and nitrogen.
1) how many volume of oxygen are required for complete combustion?
2) what is the molecular formula of the compound ?
3) what volume h2O gas measured at the same temperature and pressure is needed for complete reduction of the same volume of compound A?

Answer 1

Answer:

1) The volume of oxygen required for the complete combustion of 8.8 g of propane (C3H8) is: [C=12,O=16,H=1, Molar Volume =22.

2) The molecular formula is the actual whole number ratio between the elements in the compound. EXAMPLE: A compound with a molecular mass of 180.18 u contains 40.00% carbon, 6.72% hydrogen, and 53.28% oxygen.

3) 8ml
