Ques : 2.0 gram of a metal burst in oxygen give 3.2 gram of its oxide. 1.42 gram of the same metal heat in steam give 2.27 gram of its oxide which toys shown by this data?  Ans : In the first compound, 3.2 gram of metal oxide contained 2.0 gram of metal 100 gram of metal oxide contained metal =2.0/3.2 × 100= 62.5 g :· % metal in first compound= 62.5% In the second compound, 2.27 gram of metal oxide contains metal = 1.42 gram 100 gram of metal oxide contains the metal= 1.42/2.27×100=62.55 gram :· % metal in first compound= 62.55% Thus, the percentage of metal in metal oxide obtained from to experiment is nearly same. Hence, the above data illustrate the law of constant composition.  <<   Previous                                                       Next   >>
