A 4.09 g sample of calcium sulfide was decomposed into its constituent elements, producing 2.27 g of calcium and 1.82 g of sulfur. Which of the statements are consistent with the law of constant composition (definite proportions)? The mass ratio of S to Ca in every sample of calcium sulfide is 0.80. The ratio of calcium to sulfur will vary based on how the sample was prepared. Every sample of calcium sulfide will have 44.4% mass of sulfur. Every sample of calcium sulfide will have 2.27 g of calcium. The mass percentage of calcium plus the mass percentage of sulfur in every sample of calcium sulfide equals 100%.
