An organic substance (0.2115 g) on complete combustion gave 0.4655 g of carbon dioxide and 0.2533 g of water. Determine the percentage composition of the compound.
C = 60.03%, H = 13.30%, O = 26.67%
Mass of CO2 formed = 0.4655 g
Mass of H2O formed = 0.2533 g
Mass of the organic substance taken = 0.2115 g
Percentage of carbon
Percentage of hydrogen
Percentage of oxygen
= 100 – (60.03 + 13.30)
Composition of the substance :
C = 60.03%, H = 13.30%, O = 26.67%.
