Question -
Answer -
Percentage of carbon inorganic compound = 69 %
That is, 100 g oforganic compound contains 69 g of carbon.
∴0.2 g of organic compoundwill contain
Molecular mass of carbondioxide, CO2 = 44 g
That is, 12 g of carbonis contained in 44 g of CO2.
Therefore, 0.138 g ofcarbon will be contained in 
= 0.506 g of CO2Thus, 0.506 g of CO2 willbe produced on complete combustion of 0.2 g of organic compound.
Percentage of hydrogenin organic compound is 4.8.
i.e., 100 g of organiccompound contains 4.8 g of hydrogen.
Therefore, 0.2 g of organiccompound will contain
It is known thatmolecular mass of water (H2O) is 18 g.
Thus, 2 g of hydrogen iscontained in 18 g of water.
∴0.0096 g of hydrogen willbe contained in 
of waterThus, 0.0864 g of waterwill be produced on complete combustion of 0.2 g of the organic compound.
