7. M4 Physci Matter: Atomic Structure Slide of 46 Law of Constant Proportion For instance mass of oxygen in water is always 88.79% oxygen and 11.21% hydrogen. Mass of carbon in carbon dioxide is always 27.29% carbon and 72.71% oxygen. How does this support Democritus’ hypothesis about what matter is made up of?
