Given the following data for two compounds SnO2 and SnO . What is the whole number ratio of the oxygen of SnO  to the oxygen of SnO2 . Does this follow the law of multiple proportions?

Ratio of oxygen of SnO to  SnO2 is 13.527.1=12According to law of multiple proportions, ratio of masses of an element that combine with fixed mass of another element must be a simple whole number ratio.Element with fixed mass = Sn Element with different combining ratio = oxygenThe law of multiple proportion is obeyed.
