The statement related to law of definite proportions is

Options

  1. AThe ratio of oxygen in H 2 O and H 2 O 2 with respect to fixed mass of Hydrogen atom is a whole number
  2. B% of oxygen in H 2 O is constant irrespective of the source
  3. CEqual volume of all gases at the same temperature and pressure should contain equal number of molecules
  4. DMatter can neither be created nor destroyed.

Correct answer

B. % of oxygen in H 2 O is constant irrespective of the source

Step-by-step solution

Law of definite proportions, statement that every chemical compound contains fixed and constant proportions (by mass) of its constituent elements. % of oxygen in H 2 O is constant irrespective of the source is according to law of definite proportions The ratio of oxygen in H 2 O and H 2 O 2 with respect to fixed mass of Hydrogen atom is a whole number is according to law of multiple proportions. Equal volume of all gases at the same temperature and pressure should contain equal number of molecules is according to a
