Whole. x 100%. So…. Percent composition. of a compound or =. molecule. Compounds are ALWAYS composed of elements in fixed ratios. This is often referred to as the . Law of Definite Proportions.. This law states that elements are always present in the same proportions by mass in a compound. I.e. H. In a group, calculate the percentage of flasks, owls, . Marios. , pencils & stars. What if this was related to mass? Calculate the % by mass for each of the objects.. 100 g. 20 g. 5. 0 g. 2 g. 6. Percent Composition. Percent .
