Concept: Law of Multiple Proportions

Problem: Match each observation to the law that it illustrates:The C:O mass ratio of one compound is exactly double that of another compound. The C:O mass ratio of a particular compound is the same regardless of the size or source of the sample.When 3g of carbon reacts with 8 g of oxygen, 11 g of carbon dioxide is produced.Burning 10 g of propane produces twice as much carbon dioxide burning 5 g of propane
