Answer» law of multiple proportions, states that when TWO elements combine to form more than one compound, the mass of one element, which COMBINES with a fixed mass of the other element, will always be RATIOS of whole numbers. Let us remember that the law of multiple proportions only applies to compounds COMPOSED of the same elements. It does not apply to, let's say, SO2 and CO2 because one compound has sulfur (S) and one has carbon (C). From above explanation we can say that Only option (a) satisfies the law of multiple proportion because in N2O4 Nitrogen mass =2×14=28. Oxygen mass =16×4=64. Here 28 gram of Nitrogen combines with 64 gram of Oxygen to form 1 molecule of N2O4. While in N2O 28 gram of Nitrogen combines with 16 gram of Oxygen to form one molecule of N2O. Hence, N2O4, N2O illustrates the law of multiple proportions |
