Concept: The Conservation of Matter

# Problem: Which of the following is an example of Law of Multiple Proportions? Explain.(a) Two different samples of water are found to have the same ratio of hydrogen to oxygen. (b) When hydrogen and oxygen react to form water, the mass of water formed is exactly equal to the mass of hydrogen and oxygen that reacted. (c) The mass ratio of oxygen to hydrogen in water is 8:1. The mass ratio of oxygen to hydrogen in hydrogen peroxide (a compound that only contains hydrogen and oxygen) is 16:1.
