Question

in two experiments 0.216 gram of lead is converted into lead chloride yielding 0.348 grams in an another experiment 0.276 grams in pbcl2 .show that the data illustrates the law of composition

Answer 1

Answer:

Element     Mass   Atomic weight    Relative No. of atoms    Simplest ratio

Lead            $0.216$         $207$       $0.216/207$ $=0.0001$     $0.0001/0.03=0.003$

Chlorine      $0.348$g          $35.5$       $0.348/35.5 = 0.009$     $0.009/0.03 = 0.3$
